A tank with a square base of 20 cm was
13 filled with water After another 9600 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 9600 cm
3 of water was poured into the tank
=
35 -
13=
915 -
515=
415415 of the tank = 9600
115 of the tank = 9600 ÷ 4 = 2400
1515 of the tank = 15 x 2400 = 36000
36000 mℓ = 36 ℓ
Capacity of the tank = 36 ℓ
(b)
915 of the tank = 9 x 2400 = 21600
Final height of the water in the tank
=
2160020 x 20 = 54 cm
Answer(s): (a) 36 ℓ; (b) 54 cm
