Find the surface are of this cube 8ft 8ft 8ft

For this case we have by definition, that the surface area of a cube is given by:

Where:

l: It's the side of the cube

We have as data, according to the figure, that:

Substituting in the figure:

Thus, the surface area of the cube is

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

(23*2)-12=x     x=34
