Question

This net can be folded to form a cube with a side length of 20 units.

A cube has side lengths of 20 units.

What is the surface area of the cube in square units?

Answer 1

240 units

Explanation:

Answer 2

2400 units^2

Explanation:

If the side length is 20 units, then the area of each side is (20 units)^2, or 400 units. A cube has 6 sides.

Thus, the surface area of the cube in square units is 6(400 units^2) =

2400 units^2
