Question

Find the volume of an oil container which is 20 cm long 22 cm wide and 30 cm it is filled with oil of 21 by fifth of its volume how much oil should be pumped into the tank to it completely

Answer 1

• The volume of an oil container which is 20 cm long 22 cm wide and 30 cm is 13200 cm³ .

• If it is filled with oil by fifth of its volume, the quantity of oil that  should be pumped into the tank to fill it completely is 10560 cm³ .
• Volume is given by Length × Breadth × Height = 20 × 22 × 30 = 13200 cm³ .
• Volume required to fill the tank completely = 13200 - $\frac{13200}{5}$ = 13200 - 2640 = 10560 cm³  .
