A tank with a square base of 20 cm was
38 filled with water After another 9240 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 9240 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 9240
124 of the tank = 9240 ÷ 11 = 840
2424 of the tank = 24 x 840 = 20160
20160 mℓ = 20.16 ℓ
Capacity of the tank = 20.16 ℓ
(b)
2024 of the tank = 20 x 840 = 16800
Final height of the water in the tank
=
1680020 x 20 = 42 cm
Answer(s): (a) 20.16 ℓ; (b) 42 cm
