Question

The surface area of a cube is 864 in2. What is the area of one face of this cube?
Please explain the formula/how you got the answer

Answer 1

Divide by the number of faces and you should have your answer

Answer 2

A cube has six sides, so dividing by 6 will give you the surface area of a single face.

A single face of a cube is a square, which has an area of (side length) x (side length), so taking the square root of the area of one side of the cube will give you the length of one side of the cube. So heres the process

First divide by 6
Then take the square root
This is because cube has 6 sides
And one side is equal to the other and their product is the area of one side
864/6=144
square root of 144 = 12 feet
