surface area = 6 x 8 x 8
A cube has six equal sides; therefore, its surface area is six times the area of one of its square sides. The area of each square, in this case, is 8 x 8.
512^1/3 = 8 (inch) = length per side of cube82 = 64 = (sq inches) Area per side. There are 6 sides in a cube.64*6=384 (sq inches) Answer384 square inches surface area in a cube of volume 512 cubic inches.
There can be no such cube since, by definition, all edges of a cube have the same length.
Surface Area of a cube = 6a2 Here a = 8 cm So, S.A. = 6 x (8)2 = 6 x 64 = 384 sq. cm
