1. Since this is a cube, I believe it must have
the same value of 6.
How? See this formula:
Volume of cube = x3 or x * x * x
To get the are = X2 or x*x
Now let’s find the value of x in where the volume of the cube and 6 times the
area of its faces have the same value according to the problem:
x3 – 6x2 =0
x2 – (x - 6) = 0
Subtract 6x2 on both sides.
Thus, x = 6
