A cuboid in which all the edges are the same length is called a cube, which could also be described as a three-dimensional square. Calculating the volume of a cuboid is accomplished by multiplying the three edge lengths together. The surface area of a cuboid is equal to the sum of the areas of the rectangles that make up each side.
