A tank with a square base of 40 cm was
14 filled with water After another 67200 cm
3 of water was poured into the tank, it became
56 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 67200 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 67200
112 of the tank = 67200 ÷ 7 = 9600
1212 of the tank = 12 x 9600 = 115200
115200 mℓ = 115.2 ℓ
Capacity of the tank = 115.2 ℓ
(b)
1012 of the tank = 10 x 9600 = 96000
Final height of the water in the tank
=
9600040 x 40 = 60 cm
Answer(s): (a) 115.2 ℓ; (b) 60 cm
