Surface area of a cube with a side length of 8 cm

384cm squared.

Step-by-step explanation:

square the length of the side to get the area of one side of the cube, which is 8 x 8 = 64. Then take the area of the side and multiply it by the number of sides, which is 64 x 6 = 384. Therefore, the surface area of the cube would be 384cm squared.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
