A tank with a square base of 40 cm was
14 filled with water After another 31360 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 31360 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 31360
112 of the tank = 31360 ÷ 7 = 4480
1212 of the tank = 12 x 4480 = 53760
53760 mℓ = 53.76 ℓ
Capacity of the tank = 53.76 ℓ
(b)
1012 of the tank = 10 x 4480 = 44800
Final height of the water in the tank
=
4480040 x 40 = 28 cm
Answer(s): (a) 53.76 ℓ; (b) 28 cm
