Explanation:

Given depth ( Height ) of conical vessel = 105 cm = 10.5 decimeter ( We know 1 cm = 0.1 decimeter )

And

Diameter of conical vessel = 120 cm , So

Radius of conical vessel = 60 cm = 6 decimeter

We know : Volume of cone = πr2h3 , So

Volume of conical vessel =227× 62 × 10.53 = 22×36× 1.53= 22×12× 1.5 = 396 cubic decimeter

Given 1 cubic decimeter = 1 kg 500 gm = 1.5 kg ( We know 1 kg = 1000 gm )

Therefore,

Weight of water contained in the vessel = 396 × 1.5 = 594 kg ( Ans )
