A tank with a square base of 30 cm was
13 filled with water After another 19600 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 19600 cm
3 of water was poured into the tank
=
35 -
13=
915 -
515=
415415 of the tank = 19600
115 of the tank = 19600 ÷ 4 = 4900
1515 of the tank = 15 x 4900 = 73500
73500 mℓ = 73.5 ℓ
Capacity of the tank = 73.5 ℓ
(b)
915 of the tank = 9 x 4900 = 44100
Final height of the water in the tank
=
4410030 x 30 = 49 cm
Answer(s): (a) 73.5 ℓ; (b) 49 cm
