Texas Go Math Grade 5 Lesson 12.2 Answer Key Understand Volume

Refer to our Texas Go Math Grade 5 Answer Key Pdf to score good marks in the exams. Test yourself by practicing the problems from Texas Go Math Grade 5 Lesson 12.2 Answer Key Understand Volume.

Essential Question How can you use unit cubes to find the volume of a rectangular prism? Answer: To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units

Investigate

A. Cut out, fold, and tape the net to form a rectangular prism.

B. Use centimeter cubes to fill the base of the rectangular prism without gaps or overlaps. Each centimeter cube has a length, width, and height of 1 centimeter and a volume of 1 cubic centimeter.

• How many centimeter cubes make up the length of the first layer? the width? the height? length: 4 cm width: 5 cm height: 1 cm
• How many centimeter cubes are used to fill the base? Answer: The number of centimeter cubes that are used to fill the base is: 20-centimeter cubes

• How many centimeter cubes are in each layer? Answer: The number of centimeter cubes present in each layer is: 5 cubes
• How many layers of cubes fill the rectangular prism? Answer: The number of layers that filled the rectangular prism is: 4 layers
• How many centimeter cubes fill the prism? Answer: The number of centimeter cubes that filled the prism is: 20- centimeter cubes So, The volume of the rectangular prism is 20 cubic centimeters.

Make Connections

To find the volume of three-dimensional figures, you measure in three directions. For a rectangular prism, you measure its length, width, and height. Volume is measured using cubic units, such as cubic centimeters or cubic inches. You can also write these as cu cm or cu in.

Math Talk Mathematical processes Would the prism above be the same size if it were built with centimeter cubes, inch cubes, or foot cubes? Explain. Answer: We know that, 1 cm = 0.39 inches 1 cm = 0.032 feet Hence, The prisms will not be the same size if it were built with cubic cm, cubic in, or cubic foot

Share and Show

Compare the volumes. Write <, >, or =.

Problem Solving

Question 4. H.O.T. Connect What is the relationship between the number of centimeter cubes you used to fill each layer, the number of layers, and the volume of the prism on page 441? Answer: On page 441, The volume of the prism is: 20 cubic units The number of centimeter cubes in each layer is: 5 The number of layers is: 4 So, The relationship between the number of centimeter cubes you used to fill each layer, the number of layers, and the volume of the prism on page 441 is: The volume of the prism = (The number of layers) × (The number of centimeter cubes in each layer) Hence, from the above, We can conclude that The relationship between the number of centimeter cubes you used to fill each layer, the number of layers, and the volume of the prism on page 441 is: The volume of the prism = (The number of layers) × (The number of centimeter cubes in each layer)

Go Math Grade 5 Volume Answer Key Lesson 12.2 Question 5. H.O.T. If you had a rectangular prism that had a length of 3 units, a width of 4 units, and a height of 2 units, how many unit cubes would you need for each layer? How many unit cubes would you need to fill the rectangular prism? Answer: It is given that You had a rectangular prism that had a length of 3 units, a width of 4 units, and a height of 2 units So, The number of cubes you would need for each layer = 3 × 4 = 12 cubes So, The number of cubes you need to fill the rectangular prism = 3 × 4 × 2 = 24 units³ Hence, from the above, We can conclude that The number of cubes you would need for each layer is: 12 cubes The number of cubes you need to fill the rectangular prism is: 24 units³

Question 6. H.O.T. What’s the Error? Al says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides that measure 5 cm. Explain and correct Al’s error. Answer: It is given that Al says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides that measure 5 cm Now, The volume of the cube with side length 10 cm (x) = 10 × 10 × 10 = 1,000 cm³ The volume of the cube with side length 5 cm (y) = 5 × 5 × 5 = 125 cm³ Now, \(\frac{x}{y}\) = \(\frac{1,000}{125}\) = 8 times Hence, from the above, We can conclude that Al’s error is: A cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides that measure 5 cm The correct answer is: A cube with edges that measure 10 cm has a volume that is eight times as much as a cube with sides that measure 5 cm

Texas Go Math Grade 5 Volume Pdf Lesson 12.2 Question 8. Multi-Step A packing company makes boxes with edges each measuring 3 feet. What is the volume of a box? If 10 boxes are put in a shipping container and completely filled with no gaps or overlaps, what is the volume of the shipping container? Answer: It is given that A packing company makes boxes with edges each measuring 3 feet. and 10 boxes are put in a shipping container and completely filled with no gaps or overlaps Now, The volume of a box = 3 × 3 × 3 = 27 feet³ So, The volume of the shipping container = 27 × 10 = 270 feet³ Hence, from the above, We can conclude that The volume of a box is: 27 feet³ The volume of the shipping container is: 270 feet³

Question 4. Salim built a rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches. Would the prism Natalie built with a length of 3 inches, a width of 4 inches, and a height of 5 inches have the same volume or a different volume than Salim’s prism? Explain. Answer: It is given that Salim built a rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches. and the prism Natalie built with a length of 3 inches, a width of 4 inches, and a height of 5 inches Now, According to the given information, The volume of a rectangular prism built by Salim = 5 × 4 × 3 = 60 in.³ The volume of a rectangular prism built by Natalie = 3 × 4 × 5 = 60 in.³ Hence, from the above, We can conclude that The volume of a rectangular prism built by Salim is the same as the volume of a rectangular prism built by Natalie

Go Math 5th Grade Math Answer Key Lesson 12.2 Question 5. Oliver and Layla each built a rectangular prism with centimeter cubes. Both prisms have a volume of 24 cubic centimeters, but they do not look the same. Give possible dimensions for each prism. Answer: It is given that Oliver and Layla each built a rectangular prism with centimeter cubes. Both prisms have a volume of 24 cubic centimeters, but they do not look the same Now, The dimensions of a rectangular prism built by Oliver with a volume of 24 cubic cm = 6 cm × 2 cm × 2 cm The dimensions of a rectangular prism built by Layla with a volume of 24 cubic cm = 4cm × 2 cm × 3 cm Hence, from the above, We can conclude that The dimensions of a rectangular prism built by Oliver with a volume of 24 cubic cm is: 6 cm × 2 cm × 2 cm The dimensions of a rectangular prism built by Layla with a volume of 24 cubic cm is: 4cm × 2 cm × 3 cm
