Two similar tins have heights 12cm and 20cm.

The volume of the smaller tin is 162cm^3.

Calculate the volume, in cm^3, of the larger tin.

I got the following, not sure if it's right:

20 divided by 12 is 1.67 , so this is the scale factor.

I did 162/12 to get get 13.5 and multiplied this by 1.67 to get 22.545.

22.545 * 20 (length of large tin) is 450.9cm^3.

Am I right?
