A tank with a square base of 20 cm was
38 filled with water After another 11220 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 11220 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 11220
124 of the tank = 11220 ÷ 11 = 1020
2424 of the tank = 24 x 1020 = 24480
24480 mℓ = 24.48 ℓ
Capacity of the tank = 24.48 ℓ
(b)
2024 of the tank = 20 x 1020 = 20400
Final height of the water in the tank
=
2040020 x 20 = 51 cm
Answer(s): (a) 24.48 ℓ; (b) 51 cm
