If the volume of a cube is 8, what is the total surface area of the cube?

If the volume is 8, the length of each side is 2, ie 2 x 2 x 2

Therefore; each sides area is 4; ie 2 x 2

A cube has 6 sides

So 6 x 4 = 24 which is the total surface area.

That question doesn't make sense. But if you meant that the area of the SIDES is 8.64m2 then just do 8.64*sqrt(8.64) If you mean that the total SURFACE area is 8.64m2 then do sqrt(8.64/6)^3

Length of side = x, say
x = 8^(1/3)
Surface Area = 6 x ²
Surface Area = 6 8^(2/3)
Surface Area = ( 6 ) ( 4 ) units ²
Surface Area = 24 units ²

the length will be=(8)^1/3=2
since a cube has six surfaces total surface area of the cube will be=6*(2^2)=24 sq. unit

A cube has 8 cubic units, then each side has:
³√8
= ³√(2^3)
= 2 units

Find one of the squares' sizes:
2^2
= 2 * 2
= 4 square units

A cube has 6 equal surface, then:
4 square units * 6
= 24 square units

Volume of cube = Length x Length x Length = 8
8 = 2 x 2 x 2
Length of cube = 2 (All lengths of a cube are equal)

No. of sides of cube = 6
Area of one side = 2 x 2 = 4
Total surface area = 6 x 4 = 24

volume = a x a x a (lets a = side)
volume of a cube = 8
= 2 x 2 x 2

1 surface area = 2 x 2
= 4
all surface area (6) = 2 x 2 x 6
= 24

Volume is x^3
so in your case x=2

For surface area, you take the area times (x^2) the number of sides.
So 2^2 (4) x 6
So the answer is 24

If the volume of the cube is 8 then each side must be 2 since the formula for volume is s^3. The formula for surface area of a cube is 6s^2 so...its 6*4= 24.

Volume of a cube is calculated as W x D x H.

The cube root of 8 is 2 (2^3 = 2 x 2 x 2 = 8).

Your cube is therefore 2 x 2 x 2 = 8, so each side is 2 units wide and 2 units high.

The area of each side is calculated as W x H = 2 x 2 = 4

There are 6 sides on a cube.

Total surface area is therefore 6 sides x 4 units = 24 units.
