Question

What is the volume of a rectangular based cone?

Answer 1

See the explanation

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`
