摘要

We considered and investigated cubature formulae for determination of the 3D Fourier coefficients with usage of interflatation on the class of differentiable functions. Information about function is specified by its traces on a system of mutually perpendicular planes. It was proved, that estimate of error of cubature formulae can be expressed by certain estimates of errors of quadrature formulae.
