A tank with a square base of 30 cm was
38 filled with water After another 4950 cm
3 of water was poured into the tank, it became
56 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 4950 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 4950
124 of the tank = 4950 ÷ 11 = 450
2424 of the tank = 24 x 450 = 10800
10800 mℓ = 10.8 ℓ
Capacity of the tank = 10.8 ℓ
(b)
2024 of the tank = 20 x 450 = 9000
Final height of the water in the tank
=
900030 x 30 = 10 cm
Answer(s): (a) 10.8 ℓ; (b) 10 cm
