A tank with a square base of 50 cm was
14 filled with water After another 30625 cm
3 of water was poured into the tank, it became
35 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 30625 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 30625
120 of the tank = 30625 ÷ 7 = 4375
2020 of the tank = 20 x 4375 = 87500
87500 mℓ = 87.5 ℓ
Capacity of the tank = 87.5 ℓ
(b)
1220 of the tank = 12 x 4375 = 52500
Final height of the water in the tank
=
5250050 x 50 = 21 cm
Answer(s): (a) 87.5 ℓ; (b) 21 cm
