A container measuring 23 cm by 18 cm by 48 cm was
14 filled with water at first. Cody 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 Cody pour into container? Give your answer in mℓ.
- Cody then poured all the water in the container into several identical pitchers. Given that each pitcher can hold at least 1.2 ℓ of water, what is the least number of pitchers he would need?
(a)
Height of water in the container at first
=
14 x 48
= 12 cm
Increase in the height of water in the container
= 20 - 12
= 8 cm
Volume of water poured into the container
= 23 x 18 x 8
= 3312 mℓ
(b)
Volume of the water after some water was poured in
= 23 x 18 x 20
= 8280 cm
3
1.2 ℓ = 1200 mℓ
Number of pitchers
= 8280 ÷ 1200
= 6 r 1080
Least number of pitchers that he would need
= 6 + 1
= 7
Answer(s): (a) 3312 mℓ; (b) 7
