Question

If the surface area of a cube is 384, what is the length of one of the sides of
the cube?

Answer 1

8 units

Explanation:

Area of 1 side = 384 ÷ 6 = 64 sq units

Length of 1 side = sq.rt. (64) = 8 units Answer

Answer 2

S = 8

Each side of a face is 8 units.

Explanation:

The surface area of the cube is 384 units.

One face of the cube has an area of s^2

A cube has 6 faces

6s^2 = 384 Divide by 6

s^2 = 384 / 6

s^2 = 64 Take the square root of both sides

sqrt(s^2) = sqrt(64)

s = 8
