A tank with a square base of 30 cm was
13 filled with water After another 9450 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 9450 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 9450
115 of the tank = 9450 ÷ 7 = 1350
1515 of the tank = 15 x 1350 = 20250
20250 mℓ = 20.25 ℓ
Capacity of the tank = 20.25 ℓ
(b)
1215 of the tank = 12 x 1350 = 16200
Final height of the water in the tank
=
1620030 x 30 = 18 cm
Answer(s): (a) 20.25 ℓ; (b) 18 cm
