A tank with a square base of 30 cm was
13 filled with water After another 18800 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 18800 cm
3 of water was poured into the tank
=
35 -
13=
915 -
515=
415415 of the tank = 18800
115 of the tank = 18800 ÷ 4 = 4700
1515 of the tank = 15 x 4700 = 70500
70500 mℓ = 70.5 ℓ
Capacity of the tank = 70.5 ℓ
(b)
915 of the tank = 9 x 4700 = 42300
Final height of the water in the tank
=
4230030 x 30 = 47 cm
Answer(s): (a) 70.5 ℓ; (b) 47 cm
