    Volumes

    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?

    ?
    \left( \frac{20}{12} \right)^3 = \frac{V}{162}

    Solve for V = 750 \mbox{ cm}^3
