The figure is not drawn to scale. Container A is filled with water to a height of 25 cm. The water in Container A is poured into 2 rectangular tanks, Container B and Container C, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container A in litres.
Volume of water
= 50 x 24 x 25
= 30000 cm³ 

Combined base area
= (50 x 24) + (24 x 24) + (18 x 8)
= 1200 + 576 + 144
= 1920 cm² 

Height of water after pouring
= 30000 ÷ 1920
= 15.625 cm

Difference in the height of water
= 25 - 15.625
= 9.375 cm

Volume of water poured out of Container A
= 50 x 24 x 9.375
= 11250 cm³ 

1000 cm³ = 1 ℓ
11250 cm³ = 11250 ÷ 1000 = 11.25 ℓ

Answer(s): 11.25 ℓ
