A container measuring 22 cm by 19 cm by 48 cm was
13 filled with water at first. Flynn 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 Flynn pour into container? Give your answer in mℓ.
- Flynn then poured all the water in the container into several identical jugs. Given that each jug can hold at least 1.4 ℓ of water, what is the least number of jugs he would need?
(a)
Height of water in the container at first
=
13 x 48
= 16 cm
Increase in the height of water in the container
= 20 - 16
= 4 cm
Volume of water poured into the container
= 22 x 19 x 4
= 1672 mℓ
(b)
Volume of the water after some water was poured in
= 22 x 19 x 20
= 8360 cm
3
1.4 ℓ = 1400 mℓ
Number of jugs
= 8360 ÷ 1400
= 5 r 1360
Least number of jugs that he would need
= 5 + 1
= 6
Answer(s): (a) 1672 mℓ; (b) 6
