How surface area = volume of the cube
Why greg had done this ?
Well, he only means the value of surface area and volume
In reality, you can never equate two quantities with different units, so just ignore the units and look at the values
For eg. for a cube of side 6 cm
The surface area = 216 cm^2
The volume = 216 cm^3
Ignoring the units, the values of SA and V are the same
