A tank with a square base of 40 cm was
38 filled with water After another 25520 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 25520 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 25520
124 of the tank = 25520 ÷ 11 = 2320
2424 of the tank = 24 x 2320 = 55680
55680 mℓ = 55.68 ℓ
Capacity of the tank = 55.68 ℓ
(b)
2024 of the tank = 20 x 2320 = 46400
Final height of the water in the tank
=
4640040 x 40 = 29 cm
Answer(s): (a) 55.68 ℓ; (b) 29 cm
