In this paper, applying for the Minkowski?s and H?lder?s integral inequalities, we obtain four theorems about (p, q)-mixed volume involving Lp centroid bodies intersection bodies, respectively. The former two reveal convexity of functionals related to volume, in terms dual Blaschke addition introduced [Journal Geometric Analysis, 30 (2020) 3026-3034], latter expose monotonicity other volume.
