Abstract: In this paper, relationship of volume ratios between a symmetric convex body and its sections and projections is shown. A Blaschke-Santaló type inequality on volume ratio is proved, and some asymptotic properties of volume ratios of cubeand simplex are observed.

Key words: asymptotic property, inequality, volume ratio, convex body
