A tank with a square base of 30 cm was
25 filled with water After another 24360 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 24360 cm
3 of water was poured into the tank
=
34 -
25=
1520 -
820=
720720 of the tank = 24360
120 of the tank = 24360 ÷ 7 = 3480
2020 of the tank = 20 x 3480 = 69600
69600 mℓ = 69.6 ℓ
Capacity of the tank = 69.6 ℓ
(b)
1520 of the tank = 15 x 3480 = 52200
Final height of the water in the tank
=
5220030 x 30 = 58 cm
Answer(s): (a) 69.6 ℓ; (b) 58 cm
