See the explanation

Volume = base area $xx 1/3$ height

Let width of the base be $W$
let the length of the base be $L$

Let volume be $v$
Let area of base be $a$
Let height of pyramid be $h$

So $v=1/3ah$

But $a=LW$ giving:

$v=1/3LWh$

$LW=(3v)/h$

To solve this you must have only 1 unknown so you would need to So the only unknown has to be one if $W" or "L" or "h$
