254 units2
300 units2
314 units2
384 units2

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

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
