If you use the traditional equation for a rectangular prism where SA stands for surface area you would have. Consider a cube of length k units. SA 6 a 2.
Substituting s for the length width and height into the formulas for volume and surface area of a rectangular solid we get.
In other words we can say six times of area of one face. Or as a formula. Total surface area of cube is given by 6 k 2 k2 square units. To recall a cube is a 3 dimensional figure with 6 equal square faces 8 edges and 8 vertices.
