Solution
The correct option is A0.50l Length of the cube is 10 m. Radius of the cylinder is 4 m, and the height is 10 m. Volume of the cube = side3 =103 =1000cm3...(1) Volume of the cylinder = πr2h =π×42×10 =3.14×160 =502.4cm3...(2) Water left in the cubical vessel = (1) - (2) =1000−502.4cm3 =497.6cm3 1cm3=1ml 497.6cm3=497.6ml =0.497l =0.50l
