A container measuring 27 cm by 23 cm by 44 cm was
14 filled with water at first. Eric poured some water into the container. In the end, the height of the water level in the container was 20 cm as shown.
- How much water did Eric pour into container? Give your answer in mℓ.
- Eric then poured all the water in the container into several identical jugs. Given that each jug can hold at least 1.1 ℓ of water, what is the least number of jugs he would need?
(a)
Height of water in the container at first
=
14 x 44
= 11 cm
Increase in the height of water in the container
= 20 - 11
= 9 cm
Volume of water poured into the container
= 27 x 23 x 9
= 5589 mℓ
(b)
Volume of the water after some water was poured in
= 27 x 23 x 20
= 12420 cm
3
1.1 ℓ = 1100 mℓ
Number of jugs
= 12420 ÷ 1100
= 11 r 320
Least number of jugs that he would need
= 11 + 1
= 12
Answer(s): (a) 5589 mℓ; (b) 12
