Step-by-step explanation:
Given The capacity of a closed cistern is 9000 litters and the dimensions from outside are 3.3 m, 2.6 m and 1.2 m. The walls are 5 cm thick .Find the thickness of bottom
- Let the thickness of the bottom be t cm.
- Now length l = 3.3 m = 330 cm , breadth b = 2.6 m = 260 cm, height h = 1.2 m = 120 cm
- We need to subtract 10 cm to get the inner value.
- Now volume of cistern = l x b x h
- (330 – 10) x (260 – 10) x (120 – t) = 9000 x 1000
- 320 x 250 x (120 – t) = 9000000
- 120 – t = 9000000 / 80000
- 120 – t = 112.5
- Or t = 120 – 112.5
- Or t = 7.5 cm
- Therefore thickness of the bottom is 7.5 cm
