A tank with a square base of 10 cm was
38 filled with water After another 1485 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 1485 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 1485
124 of the tank = 1485 ÷ 11 = 135
2424 of the tank = 24 x 135 = 3240
3240 mℓ = 3.24 ℓ
Capacity of the tank = 3.24 ℓ
(b)
2024 of the tank = 20 x 135 = 2700
Final height of the water in the tank
=
270010 x 10 = 27 cm
Answer(s): (a) 3.24 ℓ; (b) 27 cm
