A tank with a square base of 10 cm was
14 filled with water After another 2750 cm
3 of water was poured into the tank, it became
45 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 2750 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 2750
120 of the tank = 2750 ÷ 11 = 250
2020 of the tank = 20 x 250 = 5000
5000 mℓ = 5 ℓ
Capacity of the tank = 5 ℓ
(b)
1620 of the tank = 16 x 250 = 4000
Final height of the water in the tank
=
400010 x 10 = 40 cm
Answer(s): (a) 5 ℓ; (b) 40 cm
