A tank with a square base of 30 cm was
13 filled with water After another 25200 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 25200 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 25200
115 of the tank = 25200 ÷ 7 = 3600
1515 of the tank = 15 x 3600 = 54000
54000 mℓ = 54 ℓ
Capacity of the tank = 54 ℓ
(b)
1215 of the tank = 12 x 3600 = 43200
Final height of the water in the tank
=
4320030 x 30 = 48 cm
Answer(s): (a) 54 ℓ; (b) 48 cm
