Question

find the total surface area of a cube with an edge of 11 ft. please show all work.

Answer 1

726

Answer 2

726
first you find one side 11 * 11 because its a cube and all the edges have the same length
then you multiply that by the number of sides which is 6 so
11*11=121
121*6 = 726

Answer 3

please explain.

Answer 4

thanks.

Answer 5

Answer 6

The total surface area of a cube is equal to 6x^2, where x is the edge or lateral of a side and the symbol in between x and 2 means the power of. We can deduce this formula because a cube has 6 sides and the total surface area of a cube is the addition of the areas of each side. The area of one side is equal to x^2 or 11^2 = 11x11= 121. To find the surface area multiply the area by six to get a final answer of 726.
