It's 18 square feet.
Six times the area of one face...
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.
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.
To create a cube, you need six square faces. Each face of the cube is a square, and the total surface area of a cube is calculated by multiplying the area of one square face by six. Therefore, regardless of the size of the cube, the number of squares needed to form its surface is always six.
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.
Total surface area of a cube = 6*area of cube face = 6*cube side*cube side
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.
The surface area of a cube can be calculated by finding the area of each of the cube's six square faces and adding them together. Since all sides of a cube are equal, the area of one face is the side length squared. Therefore, the surface area of a cube with a side length of 8mm is 6 times 8mm squared, which equals 384 square millimeters.
The formula for the surface area of a cube is (6a^2), where (a) represents the length of one edge of the cube. This formula accounts for the six identical square faces of the cube, each having an area of (a^2). To find the total surface area, you multiply the area of one face by six.
