A tank with a square base of 30 cm was
14 filled with water After another 27720 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 27720 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 27720
112 of the tank = 27720 ÷ 7 = 3960
1212 of the tank = 12 x 3960 = 47520
47520 mℓ = 47.52 ℓ
Capacity of the tank = 47.52 ℓ
(b)
1012 of the tank = 10 x 3960 = 39600
Final height of the water in the tank
=
3960030 x 30 = 44 cm
Answer(s): (a) 47.52 ℓ; (b) 44 cm
