  In a multidimensional model with several scalar fields and an m-form we deal
with classical spherically symmetric solutions with one (electric or magnetic)
p-brane and Ricci-flat internal spaces and the corresponding solutions to the
Wheeler--DeWitt (WDW) equation. Classical black holes are considered and their
quantum analogues (e.g. for M2 and M5 extremal solutions in D =11 supergravity,
electric and magnetic charges in D=4 gravity) are suggested when the curvature
coupling in the WDW equation is zero.
