A tank with a square base of 20 cm was
14 filled with water After another 18480 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 18480 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 18480
112 of the tank = 18480 ÷ 7 = 2640
1212 of the tank = 12 x 2640 = 31680
31680 mℓ = 31.68 ℓ
Capacity of the tank = 31.68 ℓ
(b)
1012 of the tank = 10 x 2640 = 26400
Final height of the water in the tank
=
2640020 x 20 = 66 cm
Answer(s): (a) 31.68 ℓ; (b) 66 cm
