### In the lessons

In school maths: a container with a volume or capacity — litres in a tank, filling or emptying at a rate; fish in a tank; volume of a box-shaped tank = length × width × height. In science: a water tank, a fuel tank; capacity and volume. In everyday life: filling the car's tank with petrol, a hot-water tank, a tank top (a shirt with no sleeves). Phrases: «a full tank», «fish tank», «petrol tank», «water tank».

### Note

Countable: «a tank». Maths: gives a capacity or holds things counted. Trap: «how long to fill» is capacity ÷ rate; when water also flows out, use the difference of the rates; «half full» means half the capacity.
