The surface area of a cube is the total sum of the area of the six sides that cover it, and it is calculated by using the formula A = 6a^2. Measure the area of one side of the cube. Multiply that number by 6 to arrive at the total surface area of the cube.Continue Reading
The formula to calculate the surface area of a cube is A = 6a^2, where a equals one edge of the cube.
Calculate the area of one side of the cube by calculating the square of the length of one side of the cube.
Multiply the area of the side of the cube by 6 to get the total surface area of the cube.
