A tank with a square base of 30 cm was
38 filled with water After another 15750 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 15750 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 15750
18 of the tank = 15750 ÷ 3 = 5250
88 of the tank = 8 x 5250 = 42000
42000 mℓ = 42 ℓ
Capacity of the tank = 42 ℓ
(b)
68 of the tank = 6 x 5250 = 31500
Final height of the water in the tank
=
3150030 x 30 = 35 cm
Answer(s): (a) 42 ℓ; (b) 35 cm
