A tank with a square base of 40 cm was
14 filled with water After another 57200 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 57200 cm
3 of water was poured into the tank
=
45 -
14=
1620 -
520=
11201120 of the tank = 57200
120 of the tank = 57200 ÷ 11 = 5200
2020 of the tank = 20 x 5200 = 104000
104000 mℓ = 104 ℓ
Capacity of the tank = 104 ℓ
(b)
1620 of the tank = 16 x 5200 = 83200
Final height of the water in the tank
=
8320040 x 40 = 52 cm
Answer(s): (a) 104 ℓ; (b) 52 cm
