2 x 2 x 2 = 8...
8 is your answer. just add the units onto it. (eg, cm cubed, m cubed)
cube root of volume gives side length, then square this to find area of one face.
If a face on a cube is 49 square meters the cube's volume is: 343 m3
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.
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.
A cube is a 3D figure. A square is a 2D shape.
49 square units because the cube root of 343 is 7 and 7*7 = 49
Each face of the cube has 1/6 of the area = 78/6 = 13 in2 .Each side of the face = square root of the area = sqrt(13) inches .The volume of the cube is (side length)3 = [ sqrt(13) ]3 = 46.872 in3 (rounded)
A cube has 6 faces of equal area. Area of each face would then be: 294 / 6 = 49 cm2. Each face is a square with edge of length equal to square root of its surface: a = sqrt(49) = 7 cm. Volume of cube is V = a3. For a = 7 cm, it would be V = 343 cm3.
You would have to specify the shape for which we are finding these quantities. But let us say that it is a cube, which is the easiest. The length of an edge of the cube, multiplied by itself gives the area of a face, and multiplied by itself again gives the volume. So the cube root of the volume is the edge length, and then the square of the edge length is the surface area of one face of the cube, which multiplied by 6 gives the area of the entire cube.
25 cm2
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.
Each face of a cube is a square. If the edges are 3-ft, then the area of each square is 9 square feet.
