A tank with a square base of 10 cm was
14 filled with water After another 2730 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 2730 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 2730
112 of the tank = 2730 ÷ 7 = 390
1212 of the tank = 12 x 390 = 4680
4680 mℓ = 4.68 ℓ
Capacity of the tank = 4.68 ℓ
(b)
1012 of the tank = 10 x 390 = 3900
Final height of the water in the tank
=
390010 x 10 = 39 cm
Answer(s): (a) 4.68 ℓ; (b) 39 cm
