There are two solids that interest us in preparing for the test. They are the rectangular solid (a box) and a circular cylinder. A cube is a special rectangular box whose sides are all equal. The volume of a box is the product of its three sides: V = bwh (base × width × height) . The volume of a circular cylinder is the area of the base times the height: V = rh (base circle × height).

The surface area of a cube is 6 × (area of one side) since all six sides have the same area. The surface area of a cylinder is composed of the top and bottom circular areas and the area around the cylinder. The top and bottom are simply 2 × × r . The area of the side is 2 × × radius × height.
