The surface of the cube is 6 times this length squared - 6L2.

Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.

The surface area is quadrupled.

Each side of the cube would be 15cm in length.

From the surface area, calculate the length of each side: area = 6 x side2.Once you know this side, you can get the cube of it, to obtain the volume.

The surface area is quadrupled.

The surface area of a cube is 6*s2 where s is the length of each side (or edge).

Surface area of a cube A = 6*L^2 where L is the length of each side. L = sqrt(A/6) = 8.

If each edge of a cube is w, then the area of each face of the cube is w2 .Since the cube has 6 faces, its total surface area is 6w2.The volume of the cube is w3 .

Surface Area of Cube is 6 x a^2 where a is the length of one side of cube. Volume of Cube is a^3 where a is the length of one side of cube.

this is incorrect -- quick example.. 2"x2"x2" cube -- will have a surface area on each side of 4"sq (2x2=4) --- now make that 4"x4"x4" -- this cube will have a surface area on each side of 16"sq (4x4=16)

Surface Area of a cube is equal to the sum of the area of it sides. Each of its sides are square of side length a. Each side has area of a2. There are 6 sides on a cube. a2 + a2+ a2+ a2+ a2+ a2 = 6a2 Therefore: Surface area of a cube is 6a2

Surface area of cube = 6 * side ^2 24/6 =4 side = sqrt (4) =2 cm

From the surface area, calculate the length of each side: area = 6 x side2.Once you know this side, you can get the cube of it, to obtain the volume.
