A tank with a square base of 30 cm was
13 filled with water After another 19000 cm
3 of water was poured into the tank, it became
34 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 19000 cm
3 of water was poured into the tank
=
34 -
13=
912 -
412=
512512 of the tank = 19000
112 of the tank = 19000 ÷ 5 = 3800
1212 of the tank = 12 x 3800 = 45600
45600 mℓ = 45.6 ℓ
Capacity of the tank = 45.6 ℓ
(b)
912 of the tank = 9 x 3800 = 34200
Final height of the water in the tank
=
3420030 x 30 = 38 cm
Answer(s): (a) 45.6 ℓ; (b) 38 cm
