A tank with a square base of 30 cm was
13 filled with water After another 9500 cm
3 of water was poured into the tank, it became
34 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 9500 cm
3 of water was poured into the tank
=
34 -
13=
912 -
412=
512512 of the tank = 9500
112 of the tank = 9500 ÷ 5 = 1900
1212 of the tank = 12 x 1900 = 22800
22800 mℓ = 22.8 ℓ
Capacity of the tank = 22.8 ℓ
(b)
912 of the tank = 9 x 1900 = 17100
Final height of the water in the tank
=
1710030 x 30 = 19 cm
Answer(s): (a) 22.8 ℓ; (b) 19 cm
