A tank with a square base of 10 cm was
14 filled with water After another 4480 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 4480 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 4480
112 of the tank = 4480 ÷ 7 = 640
1212 of the tank = 12 x 640 = 7680
7680 mℓ = 7.68 ℓ
Capacity of the tank = 7.68 ℓ
(b)
1012 of the tank = 10 x 640 = 6400
Final height of the water in the tank
=
640010 x 10 = 64 cm
Answer(s): (a) 7.68 ℓ; (b) 64 cm
