A rectangular tank measures 4m long, 2m wide and 4.8m high. Initially it is half filled with water. Find the depth of the water in the tank after 4000 litres of more water are added to it.
:
Change 4000 liters to cu/meters: 4000/1000 = 4 cu/m
:
Find the initial amt of water in the tank, half full would be:
(half the given height)
:
4 * 2 * 2.4 = 19.2 cu/meters
:
Total after 4 cu/m is added to it
19.2 + 4 = 23.2 cu/m total
:
Find the depth (d)
4 * 2 * d = 23.2
8d = 23.2
d = 23.2%2F8
d = 2.9 meter is the depth
:
:
Check solution:
4 * 2 * 2.9 = 23.2
