Question

The volume v of a wooden beam is v=ls^2 where l is the length of the beam and s is the length of one side of its square cross section. If the volume of the beam is 1200 in ^3 and its length is 96 in what is the side length?

Answer 1

\[\large V = ls^2\]

We are given V to be 1200
and l to be 96

So we need just solve for 's'

\[\large 1200 = 96\times s^2\]

Meaning

\[\large s^2 = \frac{1200}{96}\]

Or

\[\large s = \sqrt{\frac{1200}{96}}\]

Thank you !!!
