if the surface area of a cube is 48 square inches,what is the area, in square inches, of one of the faces?
If the length of one side of a cube is x then the area of that side is x².
Since a cube has 6 sides, the total surface area is 6x².
If the total surface area is 48 ---> 6x² = 48
Divide by 6: x² = 8
Find the square root: x = √8
