A tank with a square base of 30 cm was
38 filled with water After another 7200 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 7200 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 7200
18 of the tank = 7200 ÷ 3 = 2400
88 of the tank = 8 x 2400 = 19200
19200 mℓ = 19.2 ℓ
Capacity of the tank = 19.2 ℓ
(b)
68 of the tank = 6 x 2400 = 14400
Final height of the water in the tank
=
1440030 x 30 = 16 cm
Answer(s): (a) 19.2 ℓ; (b) 16 cm
