Question: If a cube has same volume (in cubic units) as surface area (in square units), what is the length of one side?

Solution:
Let,
the length of one side = s
We know,
Volume of a cube = s³,
Surface area of a cube = 6s²
According to the question,
s³ = 6s²
⇒ s = 6
So, the length of one side of that cube is 6
