Grade 6 | Unit 1 | Lesson 18: Surface Area of a Cube | Practice Problems

What is the volume of a cube with edge length 8 in?

• 512 cu in

• 64 cu in

• 256 cu in

• 128 cu in

• 32 cu in

• 1 cu cm

A cube has a volume of 8 ft³. What is its edge length?

• 2 ft

• 1.5 ft

• 3 ft

• 4 ft

• 2.5 ft

What three-dimensional figure can be assembled from this net?

• Cube

• Pyramid

• Sphere

• Cylinder

• Cone

If each square has a side length of 61 cm, write an expression for the surface area and another for the volume of the figure.

Here is a net for a rectangular prism that was not drawn accurately. Explain what is wrong with the net. Draw a net that can be assembled into a rectangular prism. Create another net for the same prism.

State whether each figure is a polyhedron. Explain how you know.

Here is Elena’s work for finding the surface area of a rectangular prism that is 1 foot by 1 foot by 2 feet. Description: rectangular prism. written "top & bottom: 2 times 12 times 12 = 2 times 144 = 288. four side faces: 4 times 2 times 1 = 8. top face 12 inches by 12 inches. Bottom face 1 foot by 1 foot. height 2 feet. She concluded that the surface area of the prism is 296 square feet. Do you agree with her? Explain your reasoning.
