A tank with a square base of 20 cm was
14 filled with water After another 17920 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 17920 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 17920
112 of the tank = 17920 ÷ 7 = 2560
1212 of the tank = 12 x 2560 = 30720
30720 mℓ = 30.72 ℓ
Capacity of the tank = 30.72 ℓ
(b)
1012 of the tank = 10 x 2560 = 25600
Final height of the water in the tank
=
2560020 x 20 = 64 cm
Answer(s): (a) 30.72 ℓ; (b) 64 cm
