How to Calculate the Area of a Cube

A cube is a three-dimensional object composed of six squares at right angles to each other. To calculate the area of a square, you multiply the length of one side by 2. To calculate the area of a cube, you take the area of a square and multiply it by 6. Thus, the formula for the cube area is 6 times the length of one side squared.

Difficulty: Easy

Instructions

Things You'll Need:

• A calculator is helpful

1. Measure the length of one side. In this example, the length is 5 inches.

2. Multiply that side by itself to get its square. In this case, 5 x 5 is 25.

3. Multiply the result by 6 to get the area of the cube. In this case, 25 * 6 equals 150 square inches.
