The figure is not drawn to scale. Container E is filled with water to a height of 25 cm. The water in Container E is poured into 2 rectangular tanks, Container F and Container G, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container E in litres.
Volume of water
= 40 x 22 x 25
= 22000 cm³ 

Combined base area
= (40 x 22) + (25 x 24) + (15 x 8)
= 880 + 600 + 120
= 1600 cm² 

Height of water after pouring
= 22000 ÷ 1600
= 13.75 cm

Difference in the height of water
= 25 - 13.75
= 11.25 cm

Volume of water poured out of Container E
= 40 x 22 x 11.25
= 9900 cm³ 

1000 cm³ = 1 ℓ
9900 cm³ = 9900 ÷ 1000 = 9.9 ℓ

Answer(s): 9.9 ℓ
