# Tanks

Fire tank has cuboid shape with a rectangular floor measuring 13.7 m × 9.8 m. Water depth is 2.4 m. Water was pumped from the tank into barrels with a capacity of 2.7 hl.

How many barrels were used, if the water level in the tank fallen 5 cm? Write the amount of water pumped as percentage.
