T = 6a^2
V = a^3
56 = 6a^2
a^2 = (28/3)
a = sqrt(28/3)
V = (28/3)^(3/2)
V = about 28.514cm^3

There are six sides to the cube, each the same size. So the area of one side is 56 divided by 6 or 9 and a third.
So you then take the square root of 9.33333+ and you get the edge.
Then you cube the edge and get the volume of about 28.5.

Let the side of the cube be x. Then, each side has a area of x^2 and hence, since the cube has 6 sides, the surface area will be 6x^2. Hence, 6x^2d = 56. Each side of the cube is x and can be found out from this equation. The volume of the cube is x^3.

divide 56 by 6 to find out that as it comes 9.3333333 multiply with square root of 9.333333 = volume of the cube =28.513804.
As the cube has six equal sides.
if u divide that by sex u will get one side surface area, then u multiply with the square root of the 9.3333333 it is 3.0550504 =
28.513804

The volume is the area divided by 6 all to the 3/2 power. Which is 28.5138 cubic centimeters

surface area = 56 sq cm
so area of one face = 56/6= 28/3
so length = (28/3) *1/2 cm
volume = (28/3) *(3/2) cu cm

dude find out the formula for surface area and then solve for a side then cube it. This problem is way too easy!

Couldn't you make it a nice round number so I could so this in my head? 54cm perhaps?
The answer would have been 27 cubic cm by the way
