A tank with a square base of 20 cm was
38 filled with water After another 2640 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 2640 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 2640
124 of the tank = 2640 ÷ 11 = 240
2424 of the tank = 24 x 240 = 5760
5760 mℓ = 5.76 ℓ
Capacity of the tank = 5.76 ℓ
(b)
2024 of the tank = 20 x 240 = 4800
Final height of the water in the tank
=
480020 x 20 = 12 cm
Answer(s): (a) 5.76 ℓ; (b) 12 cm
