Page 224: All the edges of a cube have the same length. Tony claims that the formula SA = 6s2, where s is the length of each side of the cube, can be used to calculate the surface area of the cube. Why does this formula work for cubes?

• The formula works because all edges (dimensions) are the same and every side has the same area.

• The formula works because its shorter than the formula for the rectangular prism.

• The formula works because there are 6 sides on a prism.
