Find the surface arew of a cube with a side length of 8 yards

384 yards squared

Step-by-step explanation:

since a cube is made of of 6 faces, and each faces are squares, the area of a square is s^2.

Since the surface area of a cube is the area of a square times the number of sides, the equation 8^2 x 6 can be set up.

So the answer is 384 yards^2

SA = 2LW + 2LH + 2WH

SA = 2 (8x8 + 8x8 + 8x8)

SA = 384
