A tank with a square base of 10 cm was
13 filled with water After another 2100 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 2100 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 2100
115 of the tank = 2100 ÷ 7 = 300
1515 of the tank = 15 x 300 = 4500
4500 mℓ = 4.5 ℓ
Capacity of the tank = 4.5 ℓ
(b)
1215 of the tank = 12 x 300 = 3600
Final height of the water in the tank
=
360010 x 10 = 36 cm
Answer(s): (a) 4.5 ℓ; (b) 36 cm
