A tank with a square base of 30 cm was
14 filled with water After another 13650 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 13650 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 13650
120 of the tank = 13650 ÷ 7 = 1950
2020 of the tank = 20 x 1950 = 39000
39000 mℓ = 39 ℓ
Capacity of the tank = 39 ℓ
(b)
1220 of the tank = 12 x 1950 = 23400
Final height of the water in the tank
=
2340030 x 30 = 26 cm
Answer(s): (a) 39 ℓ; (b) 26 cm
