A tank with a square base of 20 cm was
14 filled with water After another 15680 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 15680 cm
3 of water was poured into the tank
=
56 -
14=
1012 -
312=
712712 of the tank = 15680
112 of the tank = 15680 ÷ 7 = 2240
1212 of the tank = 12 x 2240 = 26880
26880 mℓ = 26.88 ℓ
Capacity of the tank = 26.88 ℓ
(b)
1012 of the tank = 10 x 2240 = 22400
Final height of the water in the tank
=
2240020 x 20 = 56 cm
Answer(s): (a) 26.88 ℓ; (b) 56 cm
