A tank with a square base of 10 cm was
14 filled with water After another 1750 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 1750 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 1750
120 of the tank = 1750 ÷ 7 = 250
2020 of the tank = 20 x 250 = 5000
5000 mℓ = 5 ℓ
Capacity of the tank = 5 ℓ
(b)
1220 of the tank = 12 x 250 = 3000
Final height of the water in the tank
=
300010 x 10 = 30 cm
Answer(s): (a) 5 ℓ; (b) 30 cm
