Наближене обчислення подвiйних iнтегралiв з використанням лагранжевої полiномiальної iнтерлiнацiї

Formula of the evaluating of multiple integrals with using Lagrange polynomial interlineation was submitted. Cubature formula is investigated in the case when information about function is set of values on lines in $G = [-1, 1]^2$ on the class of functions with condition $|f^{(p_1, p_2)} (x, y)| \le M$. The estimation of error of approaching of the cubature formula is presented.
