1. If the surface area of a cube is 294 inches squared, find the volume.
2. If the base of a prism is an equilateral triangle with sides 8cm, and each lateral edge measures 10cm, what is the volume of the prism.

A cube has 6 sides. Divide 294 by 6 to get the area of 1 side. Take the square root to get the length of a side.

Volume is s^3.
