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?
