A container measuring 30 cm by 26 cm by 44 cm was
14 filled with water at first. Fred poured some water into the container. In the end, the height of the water level in the container was 15 cm as shown.
- How much water did Fred pour into container? Give your answer in mℓ.
- Fred 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
= 15 - 11
= 4 cm
Volume of water poured into the container
= 30 x 26 x 4
= 3120 mℓ
(b)
Volume of the water after some water was poured in
= 30 x 26 x 15
= 11700 cm
3
1.4 ℓ = 1400 mℓ
Number of pitchers
= 11700 ÷ 1400
= 8 r 500
Least number of pitchers that he would need
= 8 + 1
= 9
Answer(s): (a) 3120 mℓ; (b) 9
