A tank with a square base of 30 cm was
38 filled with water After another 21150 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 21150 cm
3 of water was poured into the tank
=
34 -
38=
68 -
38=
3838 of the tank = 21150
18 of the tank = 21150 ÷ 3 = 7050
88 of the tank = 8 x 7050 = 56400
56400 mℓ = 56.4 ℓ
Capacity of the tank = 56.4 ℓ
(b)
68 of the tank = 6 x 7050 = 42300
Final height of the water in the tank
=
4230030 x 30 = 47 cm
Answer(s): (a) 56.4 ℓ; (b) 47 cm
