A tank with a square base of 10 cm was
38 filled with water After another 3150 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 3150 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 3150
18 of the tank = 3150 ÷ 3 = 1050
88 of the tank = 8 x 1050 = 8400
8400 mℓ = 8.4 ℓ
Capacity of the tank = 8.4 ℓ
(b)
68 of the tank = 6 x 1050 = 6300
Final height of the water in the tank
=
630010 x 10 = 63 cm
Answer(s): (a) 8.4 ℓ; (b) 63 cm
