A tank with a square base of 20 cm was
38 filled with water After another 15620 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 15620 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 15620
124 of the tank = 15620 ÷ 11 = 1420
2424 of the tank = 24 x 1420 = 34080
34080 mℓ = 34.08 ℓ
Capacity of the tank = 34.08 ℓ
(b)
2024 of the tank = 20 x 1420 = 28400
Final height of the water in the tank
=
2840020 x 20 = 71 cm
Answer(s): (a) 34.08 ℓ; (b) 71 cm
