The diagram shows 3 tanks of different dimensions, each separated by a partition. Tank M, measuring 55 m by 33 m by 24 m, is filled with water to its brim. Tank L is an empty cuboidal container with a length of 25 m. Slider 1 is lifted to release
13 of the water from Tank M to Tank L, after which the partition is slid down to separate Tank M and Tank L. Next, Slider 2 is removed and some water from Tank L flows into Tank K such that the height of the water level of Tank L and Tank K is 5 m.
- What is the length of Container K?
- How many m3 of water are there in Container L?
(a)
Volume of water in the Tank M that flows into the Container L
= 55 x 33 x 24 x
13 = 14520 m
3 Base area of Tank L and Tank K
= 14520 ÷ 5
= 2904 m
2 Length of Tank K and Tank L
= 2904 ÷ 33
= 88 m
Length of Tank K
= 88 - 25
= 63 m
(b)
Volume of water in Tank L
= 25 x 33 x 5
= 4125 m
3 Answer(s): (a) 63 m; (b) 4125 m
