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

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.

1. Draw a net for a cube with an edge length of cm.

2. What is the surface area of this cube?

3. What is the volume of this cube?

Here is a net for a rectangular prism that was not drawn accurately.

1. Explain what is wrong with the net.
2. Draw a net that can be assembled into a rectangular prism.
3. 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.

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.
