The figure is not drawn to scale. Container Z is filled with water to a height of 15 cm. The water in Container Z is poured into 2 rectangular tanks, Container A and Container B, such that the heights of the water in the 3 tanks are equal. Find the volume of water poured out of Container Z in litres.
Volume of water
= 40 x 22 x 15
= 13200 cm³ 

Combined base area
= (40 x 22) + (27 x 20) + (15 x 12)
= 880 + 540 + 180
= 1600 cm² 

Height of water after pouring
= 13200 ÷ 1600
= 8.25 cm

Difference in the height of water
= 15 - 8.25
= 6.75 cm

Volume of water poured out of Container Z
= 40 x 22 x 6.75
= 5940 cm³ 

1000 cm³ = 1 ℓ
5940 cm³ = 5940 ÷ 1000 = 5.94 ℓ

Answer(s): 5.94 ℓ
