A tank with a square base of 30 cm was
38 filled with water After another 17550 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 17550 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 17550
18 of the tank = 17550 ÷ 3 = 5850
88 of the tank = 8 x 5850 = 46800
46800 mℓ = 46.8 ℓ
Capacity of the tank = 46.8 ℓ
(b)
68 of the tank = 6 x 5850 = 35100
Final height of the water in the tank
=
3510030 x 30 = 39 cm
Answer(s): (a) 46.8 ℓ; (b) 39 cm
