The figure is not drawn to scale. Container K is filled with water to a height of 20 cm. The water in Container K is poured into 2 rectangular tanks, Container L and Container M, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container K in litres.
Volume of water
= 50 x 22 x 20
= 22000 cm³ 

Combined base area
= (50 x 22) + (27 x 20) + (15 x 8)
= 1100 + 540 + 120
= 1760 cm² 

Height of water after pouring
= 22000 ÷ 1760
= 12.5 cm

Difference in the height of water
= 20 - 12.5
= 7.5 cm

Volume of water poured out of Container K
= 50 x 22 x 7.5
= 8250 cm³ 

1000 cm³ = 1 ℓ
8250 cm³ = 8250 ÷ 1000 = 8.25 ℓ

Answer(s): 8.25 ℓ
