A tank with a square base of 30 cm was
38 filled with water After another 24300 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 24300 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 24300
18 of the tank = 24300 ÷ 3 = 8100
88 of the tank = 8 x 8100 = 64800
64800 mℓ = 64.8 ℓ
Capacity of the tank = 64.8 ℓ
(b)
68 of the tank = 6 x 8100 = 48600
Final height of the water in the tank
=
4860030 x 30 = 54 cm
Answer(s): (a) 64.8 ℓ; (b) 54 cm
