A tank with a square base of 20 cm was
14 filled with water After another 3500 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 3500 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 3500
120 of the tank = 3500 ÷ 7 = 500
2020 of the tank = 20 x 500 = 10000
10000 mℓ = 10 ℓ
Capacity of the tank = 10 ℓ
(b)
1220 of the tank = 12 x 500 = 6000
Final height of the water in the tank
=
600020 x 20 = 15 cm
Answer(s): (a) 10 ℓ; (b) 15 cm
