A tank with a square base of 40 cm was
14 filled with water After another 50400 cm
3 of water was poured into the tank, it became
35 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 50400 cm
3 of water was poured into the tank
=
35 -
14=
1220 -
520=
720720 of the tank = 50400
120 of the tank = 50400 ÷ 7 = 7200
2020 of the tank = 20 x 7200 = 144000
144000 mℓ = 144 ℓ
Capacity of the tank = 144 ℓ
(b)
1220 of the tank = 12 x 7200 = 86400
Final height of the water in the tank
=
8640040 x 40 = 54 cm
Answer(s): (a) 144 ℓ; (b) 54 cm
