The figure is not drawn to scale. Container L is filled with water to a height of 15 cm. The water in Container L is poured into 2 rectangular tanks, Container M and Container N, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container L in litres.
Volume of water
= 50 x 26 x 15
= 19500 cm³ 

Combined base area
= (50 x 26) + (25 x 22) + (15 x 10)
= 1300 + 550 + 150
= 2000 cm² 

Height of water after pouring
= 19500 ÷ 2000
= 9.75 cm

Difference in the height of water
= 15 - 9.75
= 5.25 cm

Volume of water poured out of Container L
= 50 x 26 x 5.25
= 6825 cm³ 

1000 cm³ = 1 ℓ
6825 cm³ = 6825 ÷ 1000 = 6.825 ℓ

Answer(s): 6.825 ℓ
