A tank with a square base of 30 cm was
13 filled with water After another 7350 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 7350 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 7350
115 of the tank = 7350 ÷ 7 = 1050
1515 of the tank = 15 x 1050 = 15750
15750 mℓ = 15.75 ℓ
Capacity of the tank = 15.75 ℓ
(b)
1215 of the tank = 12 x 1050 = 12600
Final height of the water in the tank
=
1260030 x 30 = 14 cm
Answer(s): (a) 15.75 ℓ; (b) 14 cm
