Question

A cube has a surface area of 150
cm squared. Find the side length of the cube in cm.

Answer 1

Explanation:

6 faces have an area of 150 cm^2

1 face has an area of 150/6 = 25 cm^2

The formula for the area of one face of a cube = s^2 which is the length of a side squared.

s^2 = 25

sqrt(s^2) = sqrt(25)

s = 5
