#### Answer:

I have used a instead of x. Please read the explanation

#### Explanation:

If V has three parameters, V = V (a, b, c,). Further, if their

proportions, in a units, are a : b : c = 1 : l : m, then

Example:

Volume of an ellipsoid,

Here, if b = la and c = m a,

Given that

become a, la and a/l., with l at your choice.

There is scope for giving quite a number examples, like, cube and

tetrahedron..
