Acube has a surface area of 96 sq. in. what is the length of its side?

Number of faces: 6
area of each face: side^2

Formula:
SA = 6s^2
Solve: 6s^2 = 96
s^2 = 16
side = 4 inches

A cube has 6 congruent faces shaped like a square.

The surface area is 96 sq. in.,
so each face has area 96 sq. in. / 6 = 16 sq. in.

The area of a square face is 16 sq. in.

A = s^2

s^2 = 16 sq. in.

s = 4 in.

The length of its side is 4 in.
