A tank with a square base of 30 cm was
25 filled with water After another 14280 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 14280 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 14280
120 of the tank = 14280 ÷ 7 = 2040
2020 of the tank = 20 x 2040 = 40800
40800 mℓ = 40.8 ℓ
Capacity of the tank = 40.8 ℓ
(b)
1520 of the tank = 15 x 2040 = 30600
Final height of the water in the tank
=
3060030 x 30 = 34 cm
Answer(s): (a) 40.8 ℓ; (b) 34 cm
