A tank with a square base of 40 cm was
14 filled with water After another 45920 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 45920 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 45920
112 of the tank = 45920 ÷ 7 = 6560
1212 of the tank = 12 x 6560 = 78720
78720 mℓ = 78.72 ℓ
Capacity of the tank = 78.72 ℓ
(b)
1012 of the tank = 10 x 6560 = 65600
Final height of the water in the tank
=
6560040 x 40 = 41 cm
Answer(s): (a) 78.72 ℓ; (b) 41 cm
