A tank with a square base of 50 cm was
38 filled with water After another 61875 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 61875 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 61875
124 of the tank = 61875 ÷ 11 = 5625
2424 of the tank = 24 x 5625 = 135000
135000 mℓ = 135 ℓ
Capacity of the tank = 135 ℓ
(b)
2024 of the tank = 20 x 5625 = 112500
Final height of the water in the tank
=
11250050 x 50 = 45 cm
Answer(s): (a) 135 ℓ; (b) 45 cm
