There are 80 liquorice cubes stacked in a cylindrical glass jar. The liquorice cubes have a side length of 2 cm and the glass jar has a radius of 5 cm and a height of 12 cm. How much air space remains in the jar of liquorice cubes? Give the answer correct to two decimal places.
Vair = Vjar - 80 x Vliquorice cube
= pi xx r^2 xx h - 80 xx l^3
= pi xx 5^2 xx 12 - 80 xx 2^3
= 942.477796 - 640
= 302.48 cm3
