The mass of an ornament is m grams. The height of the ornament is h centimetres.
m is directly proportional to the cube of h.
m = 525 when h= 5
a) Work out an equation connecting m and h.

Given:

m is directly proportional to the cube of h.

m = 525 when h= 5.

To find:

The equation connecting m and h.

Solution:

m is directly proportional to the cube of h.

           ...(i)

Where, k is the constant of proportionality.

Putting m = 525 and h= 5, we get

Putting k=105 in (i), we get

Therefore, the required equation is .
