how to find the surface area and volume of a rectangular prism with a square base, sides of 8 1/2 inches and a height of 12 2/3 inches?

Volume, just multiply all 3 lengths together. 8 1/2 * 8 1/2 * 12 2/3

Surface area ad all the combinations of multipling 2 terms times 2. 2((8 1/2 * 8 1/2) + (8 1/2 * 12 2/3) + (8 1/2 * 12 2/3))
