A tank with a square base of 40 cm was
14 filled with water After another 81760 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 81760 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 81760
112 of the tank = 81760 ÷ 7 = 11680
1212 of the tank = 12 x 11680 = 140160
140160 mℓ = 140.16 ℓ
Capacity of the tank = 140.16 ℓ
(b)
1012 of the tank = 10 x 11680 = 116800
Final height of the water in the tank
=
11680040 x 40 = 73 cm
Answer(s): (a) 140.16 ℓ; (b) 73 cm
