A tank with a square base of 50 cm was
38 filled with water After another 20625 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 20625 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 20625
124 of the tank = 20625 ÷ 11 = 1875
2424 of the tank = 24 x 1875 = 45000
45000 mℓ = 45 ℓ
Capacity of the tank = 45 ℓ
(b)
2024 of the tank = 20 x 1875 = 37500
Final height of the water in the tank
=
3750050 x 50 = 15 cm
Answer(s): (a) 45 ℓ; (b) 15 cm
