Question

If each side of the cube measures 3 inches, what is the surface area of the cube in square inches?

Answer 1

54in^2

Explanation:

The formula for the surface area of a rectangular prism or cube is:

2(length*width + length*height + width*height). In this case, we get:

2(3*3 + 3*3 + 3*3), which is

2(9+9+9), which is

2(27), which is

54.
