The fire tank has a 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 a percentage.

Correct answer:

n =  25
p =  2.08 %

Step-by-step explanation:

V= m3 V1= m3 V2=2.7 hl=0.27 m3  n=V1V225
