A rectangular tank measuring 60 cm by 54 cm by 35 cm was filled with water to a height of 24 cm at first. After 9 completely filled identical jugs of water were poured into the tank, the new water level in the tank became 33 cm.
- Find the volume of water in each jug in cubic centimetres.
- How much more water would be needed to fill the tank completely? (Give your answer in litres.)
(a)
Difference in the height of the new and old water level
= 33 - 24
= 9 cm
Total volume of water added
= 54 x 60 x 9
= 29160 cm
3 Volume of water in each jug
= 29160 ÷ 9
= 3240 cm
3 (b)
Difference in the height of the tank and the water after 9 jugs of water were poured in
= 35 - 33
= 2 cm
Volume of water needed to fill the tank completely
= 54 x 60 x 2
= 6480 cm
3 1000 cm
3 = 1 ℓ
6480 cm
3 = 6.48 ℓ
Answer(s): (a) 3240 cm
3; (b) 6.48 ℓ
