A tank with a square base of 40 cm was
25 filled with water After another 49280 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 49280 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 49280
120 of the tank = 49280 ÷ 7 = 7040
2020 of the tank = 20 x 7040 = 140800
140800 mℓ = 140.8 ℓ
Capacity of the tank = 140.8 ℓ
(b)
1520 of the tank = 15 x 7040 = 105600
Final height of the water in the tank
=
10560040 x 40 = 66 cm
Answer(s): (a) 140.8 ℓ; (b) 66 cm
