A tank with a square base of 40 cm was
14 filled with water After another 20160 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 20160 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 20160
112 of the tank = 20160 ÷ 7 = 2880
1212 of the tank = 12 x 2880 = 34560
34560 mℓ = 34.56 ℓ
Capacity of the tank = 34.56 ℓ
(b)
1012 of the tank = 10 x 2880 = 28800
Final height of the water in the tank
=
2880040 x 40 = 18 cm
Answer(s): (a) 34.56 ℓ; (b) 18 cm
