Question 1159968
Length, L
Width, w
Depth, h
Volume is   {{{Lwh}}}



You know that {{{(2w)w*2=2500}}} from the description.
This is only a single unknown variable, so you could use the given values and information instead of using them all as variables.


{{{w^2=2500/4}}}

{{{w^2=25*25}}}

{{{highlight(w=25)}}} and you can find L.
