216 square inches
The surface of the cube is 6 times this length squared - 6L2.
6 * 8.52 = 433.5
216 square inches.
Surface area of a cube A = 6*L^2 where L is the length of each side. L = sqrt(A/6) = 8.
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
6*6*6 = 216 cubic inches
6 * ((7 inches) * 7 inches) = 294 inches^2
It is: 3*3*6 = 54 square inches
If the length of the side is S, the area of the faces of the cube is 6*S^2. There are six faces to the cube, and each face is S*S. For example, if the side of the cube is 2 inches, the area of a face is 2*2 = 4 square inches. Six faces means the overall area is 6*4 = 24 square inches.
The volume of any cube is the cube or third power of the length of one of its sides. In this instance, (6 inches)3 equals 216 cubic inches.
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.
