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

The net, when folded into a cube, has a total surface area of 2,400 sq. units

Step-by-step explanation:

The length of all sides of a cube are the same.

Now, the surface area of a cube is the sum of the area of all of its faces.

Since the length of all sides are the same and we are told that the length of a side is 20 units, thus, the area of one face is;

A = 20 x 20 = 400 sq. units

So, one the area of a face is 400 sq. units.

Now, since all the faces are the same measurement, thus each face will have an area of 400 sq. units. Cubes have 6 faces, thus the total surface Area is;

Total = 400 x 6 = 2400 sq. units

The net, when folded into a cube, has a total surface area of 2,400 sq. units
