A tank with a square base of 50 cm was
38 filled with water After another 64625 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 64625 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 64625
124 of the tank = 64625 ÷ 11 = 5875
2424 of the tank = 24 x 5875 = 141000
141000 mℓ = 141 ℓ
Capacity of the tank = 141 ℓ
(b)
2024 of the tank = 20 x 5875 = 117500
Final height of the water in the tank
=
11750050 x 50 = 47 cm
Answer(s): (a) 141 ℓ; (b) 47 cm
