A tank with a square base of 20 cm was
13 filled with water After another 18200 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 18200 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 18200
115 of the tank = 18200 ÷ 7 = 2600
1515 of the tank = 15 x 2600 = 39000
39000 mℓ = 39 ℓ
Capacity of the tank = 39 ℓ
(b)
1215 of the tank = 12 x 2600 = 31200
Final height of the water in the tank
=
3120020 x 20 = 78 cm
Answer(s): (a) 39 ℓ; (b) 78 cm
