A tank with a square base of 30 cm was
38 filled with water After another 5445 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 5445 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 5445
124 of the tank = 5445 ÷ 11 = 495
2424 of the tank = 24 x 495 = 11880
11880 mℓ = 11.88 ℓ
Capacity of the tank = 11.88 ℓ
(b)
2024 of the tank = 20 x 495 = 9900
Final height of the water in the tank
=
990030 x 30 = 11 cm
Answer(s): (a) 11.88 ℓ; (b) 11 cm
