A tank with a square base of 20 cm was
14 filled with water After another 11200 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 11200 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 11200
120 of the tank = 11200 ÷ 7 = 1600
2020 of the tank = 20 x 1600 = 32000
32000 mℓ = 32 ℓ
Capacity of the tank = 32 ℓ
(b)
1220 of the tank = 12 x 1600 = 19200
Final height of the water in the tank
=
1920020 x 20 = 48 cm
Answer(s): (a) 32 ℓ; (b) 48 cm
