A tank with a square base of 50 cm was
38 filled with water After another 72875 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 72875 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 72875
124 of the tank = 72875 ÷ 11 = 6625
2424 of the tank = 24 x 6625 = 159000
159000 mℓ = 159 ℓ
Capacity of the tank = 159 ℓ
(b)
2024 of the tank = 20 x 6625 = 132500
Final height of the water in the tank
=
13250050 x 50 = 53 cm
Answer(s): (a) 159 ℓ; (b) 53 cm
