Question

A cube has a surface area of 24 ft squared .What is the length of on edge of the cube?

Answer 1

Surface area= 24 ft^2

A cube has 6 faces, so the surface area of 1 face would be 24/6, which is 4 ft^2.

The formula for the area of a square is l x w, but in a square both are equal so you're essentially squaring one side.

Therefore, the area of a square ( 4 ft^2 ) can be square-rooted in order to find the length of an edge.

$\sqrt{4}$ = 2

Therefore, the length of 1 edge of the cube is 2 ft
