We study three-body nonleptonic decays B\ensuremath→VVP by introducing two-meson distribution amplitudes for the vector-pseudoscalar pair, such that the analysis is simplified into the one for two-body decays. The twist-2 and twist-3 \ensuremathφK two-meson distribution amplitudes, associated with longitudinally and transversely polarized \ensuremathφ mesons, are constrained by the experimental data of the \ensuremathτ\ensuremath→\ensuremathφK\ensuremathν and B\ensuremath→\ensuremathφK\ensuremathγ branching ratios. We then predict the B\ensuremath→\ensuremathφK\ensuremathγ and B\ensuremath→\ensuremathφ\ensuremathφK decay spectra in the \ensuremathφK invariant mass. Since the resonant contribution in the \ensuremathφK channel is negligible, the above decay spectra provide a clean test for the application of two-meson distribution amplitudes to three-body B meson decays.
