A tank with a square base of 30 cm was
25 filled with water After another 13860 cm
3 of water was poured into the tank, it became
34 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 13860 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 13860
120 of the tank = 13860 ÷ 7 = 1980
2020 of the tank = 20 x 1980 = 39600
39600 mℓ = 39.6 ℓ
Capacity of the tank = 39.6 ℓ
(b)
1520 of the tank = 15 x 1980 = 29700
Final height of the water in the tank
=
2970030 x 30 = 33 cm
Answer(s): (a) 39.6 ℓ; (b) 33 cm
