A tank with a square base of 10 cm was
14 filled with water After another 2100 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 2100 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 2100
112 of the tank = 2100 ÷ 7 = 300
1212 of the tank = 12 x 300 = 3600
3600 mℓ = 3.6 ℓ
Capacity of the tank = 3.6 ℓ
(b)
1012 of the tank = 10 x 300 = 3000
Final height of the water in the tank
=
300010 x 10 = 30 cm
Answer(s): (a) 3.6 ℓ; (b) 30 cm
