.
80 mm = 8 cm


1 liter = 1000 cm^3.


The answer is 1000%2F%288%2A8%29 = 15.625 cm = 156.25 mm.

a rectangular water jug has a square base 80mm by 80mm
what must be the height h of the jug in mm if it is to contain 1 litre of water
first, you are looking for a volume:
V=a%2Ab%2Ah where a=80mm, b=80mm, and since 1 litre of water equals to 1000000mm%5E3, we have

1000000mm%5E3=80mm%2A80mm%2Ah
1000000mm%5E3=6400mm%5E2%2Ah
h=10000cross%2800%29mm%5Ecross%283%29%2F64cross%2800%29cross%28mm%5E2%29
h=10000mm%2F64
h=156.25mm
