(a) The capacity of the tank is its volume, which we can calculate by multipling its sides:


V=abc=60\cdot50\cdot56=168000

This is, 168000 cm³. It is equivalent to 168 L.

(b) If the tank is being filled at a rate of 8 liters per minute, we can find the time to fill ir by dividing its capacity by the rate:


t=(168)/(8)=21

That is, it will take 21 minutos to fill it up.
