cube has 6 faces that are square
area of square=side^2
side=8
SA=6s^2
SA=6(8^2)
SA=6(64)
SA=384 ft^2
Solutions 

Finding the sum of all the areas of each face on a 3-D object is called calculating the surface area. 

We know that we have to find the SA of a cube. A cube has 6 faces and all the sides are same. 

Calculations 

SA=6s²

SA=6(8²)

SA=6(64)

SA=384 ft²
