A tank with a square base of 50 cm was
13 filled with water After another 65625 cm
3 of water was poured into the tank, it became
45 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 65625 cm
3 of water was poured into the tank
=
45 -
13=
1215 -
515=
715715 of the tank = 65625
115 of the tank = 65625 ÷ 7 = 9375
1515 of the tank = 15 x 9375 = 140625
140625 mℓ = 140.625 ℓ
Capacity of the tank = 140.625 ℓ
(b)
1215 of the tank = 12 x 9375 = 112500
Final height of the water in the tank
=
11250050 x 50 = 45 cm
Answer(s): (a) 140.625 ℓ; (b) 45 cm
