A tank with a square base of 10 cm was
38 filled with water After another 3630 cm
3 of water was poured into the tank, it became
56 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 3630 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 3630
124 of the tank = 3630 ÷ 11 = 330
2424 of the tank = 24 x 330 = 7920
7920 mℓ = 7.92 ℓ
Capacity of the tank = 7.92 ℓ
(b)
2024 of the tank = 20 x 330 = 6600
Final height of the water in the tank
=
660010 x 10 = 66 cm
Answer(s): (a) 7.92 ℓ; (b) 66 cm
