384 units2

Step-by-step explanation:

Hi there! Hopefully this helps!

384 unit²

Step-by-step explanation:

If we have a square prism with all sides equal, we are in the presence of a cube. A cube has six identical faces. We can calculate the surface area of each face:

Area = side × side = side²

If the length of the side is eight units, the area of each face is:

A = side² = (8 unit)² = 64 unit²

The total surface area of the square prism is the surface area of 1 face times 6.

64 unit² × 6 = 384 unit²
