A tank with a square base of 10 cm was
38 filled with water After another 3600 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 3600 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 3600
18 of the tank = 3600 ÷ 3 = 1200
88 of the tank = 8 x 1200 = 9600
9600 mℓ = 9.6 ℓ
Capacity of the tank = 9.6 ℓ
(b)
68 of the tank = 6 x 1200 = 7200
Final height of the water in the tank
=
720010 x 10 = 72 cm
Answer(s): (a) 9.6 ℓ; (b) 72 cm
