A container measuring 29 cm by 25 cm by 55 cm was
15 filled with water at first. Fabian poured some water into the container. In the end, the height of the water level in the container was 14 cm as shown.
- How much water did Fabian pour into container? Give your answer in mℓ.
- Fabian then poured all the water in the container into several identical jugs. Given that each jug can hold at least 1.2 ℓ of water, what is the least number of jugs he would need?
(a)
Height of water in the container at first
=
15 x 55
= 11 cm
Increase in the height of water in the container
= 14 - 11
= 3 cm
Volume of water poured into the container
= 29 x 25 x 3
= 2175 mℓ
(b)
Volume of the water after some water was poured in
= 29 x 25 x 14
= 10150 cm
3
1.2 ℓ = 1200 mℓ
Number of jugs
= 10150 ÷ 1200
= 8 r 550
Least number of jugs that he would need
= 8 + 1
= 9
Answer(s): (a) 2175 mℓ; (b) 9
