A tank with a square base of 10 cm was
38 filled with water After another 990 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 990 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 990
124 of the tank = 990 ÷ 11 = 90
2424 of the tank = 24 x 90 = 2160
2160 mℓ = 2.16 ℓ
Capacity of the tank = 2.16 ℓ
(b)
2024 of the tank = 20 x 90 = 1800
Final height of the water in the tank
=
180010 x 10 = 18 cm
Answer(s): (a) 2.16 ℓ; (b) 18 cm
