A tank with a square base of 20 cm was
38 filled with water After another 8580 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 8580 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 8580
124 of the tank = 8580 ÷ 11 = 780
2424 of the tank = 24 x 780 = 18720
18720 mℓ = 18.72 ℓ
Capacity of the tank = 18.72 ℓ
(b)
2024 of the tank = 20 x 780 = 15600
Final height of the water in the tank
=
1560020 x 20 = 39 cm
Answer(s): (a) 18.72 ℓ; (b) 39 cm
