determine the length of one edge of a cube that has a surface area of 864 square inches.
The surface of the cube is 6 times this length squared - 6L2.
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
The edge length is 5 inches.
294 square inches
The surface area of a cube with an edge length of 5 inches is 150 square inches.
determine the length of one edge of a cube that has a surface area of 864 square inches.
The edge length is 7.35 inches.
The surface of the cube is 6 times this length squared - 6L2.
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
The edge length is 5 inches.
294 square inches
216 square inches
Volume = 11x11x11 = 1331 inches Surface area = 11x11x6 = 726 inches
6 * 8.52 = 433.5
Surface area of a cube A = 6*L^2 where L is the length of each side. L = sqrt(A/6) = 8.
SA = 294 square inches.
