A tank with a square base of 40 cm was
14 filled with water After another 69440 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 69440 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 69440
112 of the tank = 69440 ÷ 7 = 9920
1212 of the tank = 12 x 9920 = 119040
119040 mℓ = 119.04 ℓ
Capacity of the tank = 119.04 ℓ
(b)
1012 of the tank = 10 x 9920 = 99200
Final height of the water in the tank
=
9920040 x 40 = 62 cm
Answer(s): (a) 119.04 ℓ; (b) 62 cm
