A tank with a square base of 10 cm was
14 filled with water After another 1680 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 1680 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 1680
112 of the tank = 1680 ÷ 7 = 240
1212 of the tank = 12 x 240 = 2880
2880 mℓ = 2.88 ℓ
Capacity of the tank = 2.88 ℓ
(b)
1012 of the tank = 10 x 240 = 2400
Final height of the water in the tank
=
240010 x 10 = 24 cm
Answer(s): (a) 2.88 ℓ; (b) 24 cm
