A tank with a square base of 30 cm was
38 filled with water After another 13950 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 13950 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 13950
18 of the tank = 13950 ÷ 3 = 4650
88 of the tank = 8 x 4650 = 37200
37200 mℓ = 37.2 ℓ
Capacity of the tank = 37.2 ℓ
(b)
68 of the tank = 6 x 4650 = 27900
Final height of the water in the tank
=
2790030 x 30 = 31 cm
Answer(s): (a) 37.2 ℓ; (b) 31 cm
