Yogesh,
First you need to convert the measurement units to meters. There are 2.54 cm in an inch so your roll is
2.54 63 = 160.02 cm which is 1.60 meters long
and
2.54 11 = 27.94 cm which is 0.279 meters in diameter.
The volume of a cylinder is r^{2} h where r is the radius and h is the height. Thus the volume of your roll is
( ^{0.2794}/_{2})^{2} 1.60 = 0.098 cubic meters
which is approximately one tenth of a cubic meter
