The diagram shows 3 tanks of different dimensions, each separated by a partition. Tank J, measuring 60 m by 39 m by 26 m, is filled with water to its brim. Tank H is an empty cuboidal container with a length of 21 m. Slider 1 is lifted to release
15 of the water from Tank J to Tank H, after which the partition is slid down to separate Tank J and Tank H. Next, Slider 2 is removed and some water from Tank H flows into Tank G such that the height of the water level of Tank H and Tank G is 6 m.
- What is the length of Tank G?
- How many m3 of water are there in Tank H?
(a)
Volume of water in the Tank J that flows into the Tank H
= 60 x 39 x 26 x
15 = 12168 m
3 Base area of Tank H and Tank G
= 12168 ÷ 6
= 2028 m
2 Length of Tank G and Tank H
= 2028 ÷ 39
= 52 m
Length of Tank G
= 52 - 21
= 31 m
(b)
Volume of water in Tank H
= 21 x 39 x 6
= 4914 m
3 Answer(s): (a) 31 m; (b) 4914 m
