A tank with a square base of 10 cm was
14 filled with water After another 3640 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 3640 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 3640
112 of the tank = 3640 ÷ 7 = 520
1212 of the tank = 12 x 520 = 6240
6240 mℓ = 6.24 ℓ
Capacity of the tank = 6.24 ℓ
(b)
1012 of the tank = 10 x 520 = 5200
Final height of the water in the tank
=
520010 x 10 = 52 cm
Answer(s): (a) 6.24 ℓ; (b) 52 cm
