7. A rectangular tank measures 4 m long, 2 m wide and 4.8 m high. Initially it is half filled with
water. Find the depth of water in the tank after 4 000 litres more of water are added to it.​

Answer 1

tank volume 38.4 cu m=38400 l

3/4 full=38400 x 3/4=28800 l

32800/38400= .854 fll

tank 4,8 m tall x 854 current water level= 4.1 m depth of water
