A tank with a square base of 20 cm was
14 filled with water After another 11760 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 11760 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 11760
112 of the tank = 11760 ÷ 7 = 1680
1212 of the tank = 12 x 1680 = 20160
20160 mℓ = 20.16 ℓ
Capacity of the tank = 20.16 ℓ
(b)
1012 of the tank = 10 x 1680 = 16800
Final height of the water in the tank
=
1680020 x 20 = 42 cm
Answer(s): (a) 20.16 ℓ; (b) 42 cm
