A tank with a square base of 20 cm was
13 filled with water After another 4800 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 4800 cm
3 of water was poured into the tank
=
35 -
13=
915 -
515=
415415 of the tank = 4800
115 of the tank = 4800 ÷ 4 = 1200
1515 of the tank = 15 x 1200 = 18000
18000 mℓ = 18 ℓ
Capacity of the tank = 18 ℓ
(b)
915 of the tank = 9 x 1200 = 10800
Final height of the water in the tank
=
1080020 x 20 = 27 cm
Answer(s): (a) 18 ℓ; (b) 27 cm
