A tank with a square base of 30 cm was
13 filled with water After another 11200 cm
3 of water was poured into the tank, it became
35 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 11200 cm
3 of water was poured into the tank
=
35 -
13=
915 -
515=
415415 of the tank = 11200
115 of the tank = 11200 ÷ 4 = 2800
1515 of the tank = 15 x 2800 = 42000
42000 mℓ = 42 ℓ
Capacity of the tank = 42 ℓ
(b)
915 of the tank = 9 x 2800 = 25200
Final height of the water in the tank
=
2520030 x 30 = 28 cm
Answer(s): (a) 42 ℓ; (b) 28 cm
