  Consider some convex body $K\subset\mathbb R^d$. Let $X_1,\dots, X_k$, where
$k\leq d$, be random points independently and uniformly chosen in $K$, and let
$\xi_k$ be a uniformly distributed random linear $k$-plane. We show that for
$p\geq-d+k+1$, \[ \mathbb E\,|K\cap\xi_k|^{d+p}\leq c_{d,k,p} \cdot|K|^k\,
\,\mathbb E\,|\mathrm{conv}(0,X_1, \dots,X_k)|^p, \] where $|\cdot|$ and
$\mathrm{conv}$ denote the volume of correspondent dimension and the convex
hull. The constant $c_{d,k,p}$ is such that for $k>1$ the equality holds if and
only if $K$ is an ellipsoid centered at the origin, and for $k=1$ the
inequality turns to equality. If $p=0$, then the inequality reduces to the
Busemann intersection inequality, and if $k=d$ -- to the Busemann random
simplex inequality. We also present an affine version of this inequality which
similarly generalizes the Schneider inequality and the Blaschke-Gr\"omer
inequality.
