A tank with a square base of 30 cm was
13 filled with water After another 6825 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 6825 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 6825
115 of the tank = 6825 ÷ 7 = 975
1515 of the tank = 15 x 975 = 14625
14625 mℓ = 14.625 ℓ
Capacity of the tank = 14.625 ℓ
(b)
1215 of the tank = 12 x 975 = 11700
Final height of the water in the tank
=
1170030 x 30 = 13 cm
Answer(s): (a) 14.625 ℓ; (b) 13 cm
