A tank with a square base of 20 cm was
38 filled with water After another 17380 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 17380 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 17380
124 of the tank = 17380 ÷ 11 = 1580
2424 of the tank = 24 x 1580 = 37920
37920 mℓ = 37.92 ℓ
Capacity of the tank = 37.92 ℓ
(b)
2024 of the tank = 20 x 1580 = 31600
Final height of the water in the tank
=
3160020 x 20 = 79 cm
Answer(s): (a) 37.92 ℓ; (b) 79 cm
