Six times the area of one face...
4 square cm
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.
A cube with a face diagonal of 25cm has a surface area of 1875cm2
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.
Total surface area of a cube = 6*area of cube face = 6*cube side*cube side
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
The surface area of each face is 16 and there are 6 faces so the total surface area is 16x6 or 96 square units.
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.
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.
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.
