A rectangular tank measuring 63 cm by 48 cm by 36 cm was filled with water to a height of 25 cm at first. After 8 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 - 25
= 8 cm
Total volume of water added
= 48 x 63 x 8
= 24192 cm
3 Volume of water in each jug
= 24192 ÷ 8
= 3024 cm
3 (b)
Difference in the height of the tank and the water after 8 jugs of water were poured in
= 36 - 33
= 3 cm
Volume of water needed to fill the tank completely
= 48 x 63 x 3
= 9072 cm
3 1000 cm
3 = 1 ℓ
9072 cm
3 = 9.072 ℓ
Answer(s): (a) 3024 cm
3; (b) 9.072 ℓ
