Question

The base of a rectangular solid is a square with a side of the length a cm. The height of the rectangular solid is b cm and its volume is equal to Vcm³. Express the variable a in terms of b and V.

Answer 1

The base has an area of $a^2$

So, the volume is $V=a^2b$

Solving for a, you get $a=\sqrt{\frac{V}{b}} =\frac{\sqrt{Vb}}{b}$
