A tank with a square base of 40 cm was
14 filled with water After another 19800 cm
3 of water was poured into the tank, it became
45 full.
- Find the capacity of the tank in litres.
- Find the final height of the water in the tank.
(a)
Fraction of the tank when 19800 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 19800
120 of the tank = 19800 ÷ 11 = 1800
2020 of the tank = 20 x 1800 = 36000
36000 mℓ = 36 ℓ
Capacity of the tank = 36 ℓ
(b)
1620 of the tank = 16 x 1800 = 28800
Final height of the water in the tank
=
2880040 x 40 = 18 cm
Answer(s): (a) 36 ℓ; (b) 18 cm
