A tank with a square base of 10 cm was
13 filled with water After another 4200 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 4200 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 4200
115 of the tank = 4200 ÷ 7 = 600
1515 of the tank = 15 x 600 = 9000
9000 mℓ = 9 ℓ
Capacity of the tank = 9 ℓ
(b)
1215 of the tank = 12 x 600 = 7200
Final height of the water in the tank
=
720010 x 10 = 72 cm
Answer(s): (a) 9 ℓ; (b) 72 cm
