It's 18 square feet.
The total surface area of a cube would be 6 x area-of-one-cube-face (there are 6 faces to a cube). Each face of a cube is a square. If any edge of the cube is "a", then: 6 x a x a.
Six times the area of one face...
4 square cm
The easiest way to find the volume of a cube is to find the length of its edgeand then cube that number.Here's how to find the length of the edge from the total surface area:-- A cube has 6 faces. If its total surface area is 96 square units, thenthe area of each face is 16 square units.-- Each face is a square. If the area of the square is 16 square units, thenthe side of the square is 4 units.But the side of the square face is the same as the edge of the cube !-- The volume of the cube is (4 x 4 x 4) = 64 cubic units.
A cube with a face diagonal of 25cm has a surface area of 1875cm2
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
Divide the surface area by six. That will give you the area of one face, which will be a perfect square. The square root of that number will give you the length of a side. The cube of the side will be the volume.
Total surface area of a cube = 6*area of cube face = 6*cube side*cube side
216 square inch total surface area, divide that by 6 to have the area of each square face, 36 square inch. The square root of that is the length of one side, 6 inches.
The surface area of each face is 16 and there are 6 faces so the total surface area is 16x6 or 96 square units.
Cube root of 216 = 6 units Therefore each face is 6*6 units which = 36 square units A cube has 6 faces, so 6*36 = 216 square units which is the surface area of the cube.
A cube has 6 faces. Each face will be 7.5 times 7.5 = 56.25 square inches. Therefore the surface area of the culbe will be 6 times 56.25 = 337.5 square inches.
