A container measuring 22 cm by 19 cm by 48 cm was
13 filled with water at first. Oliver poured some water into the container. In the end, the height of the water level in the container was 25 cm as shown.
- How much water did Oliver pour into container? Give your answer in mℓ.
- Oliver then poured all the water in the container into several identical bottles. Given that each bottle can hold at least 1.3 ℓ of water, what is the least number of bottles 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
= 25 - 16
= 9 cm
Volume of water poured into the container
= 22 x 19 x 9
= 3762 mℓ
(b)
Volume of the water after some water was poured in
= 22 x 19 x 25
= 10450 cm
3
1.3 ℓ = 1300 mℓ
Number of bottles
= 10450 ÷ 1300
= 8 r 50
Least number of bottles that he would need
= 8 + 1
= 9
Answer(s): (a) 3762 mℓ; (b) 9
