A tank with a square base of 20 cm was
14 filled with water After another 14300 cm
3 of water was poured into the tank, it became
45 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 14300 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 14300
120 of the tank = 14300 ÷ 11 = 1300
2020 of the tank = 20 x 1300 = 26000
26000 mℓ = 26 ℓ
Capacity of the tank = 26 ℓ
(b)
1620 of the tank = 16 x 1300 = 20800
Final height of the water in the tank
=
2080020 x 20 = 52 cm
Answer(s): (a) 26 ℓ; (b) 52 cm
