The figure is not drawn to scale. Container S is filled with water to a height of 15 cm. The water in Container S is poured into 2 rectangular tanks, Container T and Container U, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container S in litres.
Volume of water
= 50 x 24 x 15
= 18000 cm³ 

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

Height of water after pouring
= 18000 ÷ 1920
= 9.375 cm

Difference in the height of water
= 15 - 9.375
= 5.625 cm

Volume of water poured out of Container S
= 50 x 24 x 5.625
= 6750 cm³ 

1000 cm³ = 1 ℓ
6750 cm³ = 6750 ÷ 1000 = 6.75 ℓ

Answer(s): 6.75 ℓ
