A container measuring 28 cm by 24 cm by 44 cm was
14 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 pitchers. Given that each pitcher can hold at least 1.4 ℓ of water, what is the least number of pitchers 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
= 28 x 24 x 9
= 6048 mℓ
(b)
Volume of the water after some water was poured in
= 28 x 24 x 20
= 13440 cm
3
1.4 ℓ = 1400 mℓ
Number of pitchers
= 13440 ÷ 1400
= 9 r 840
Least number of pitchers that he would need
= 9 + 1
= 10
Answer(s): (a) 6048 mℓ; (b) 10
