The video tutorial explains how to evaluate a triple integral using a change of variables. It begins by introducing the concept of a triple integral and the function f(x, y, z). The tutorial then details how to set new integration limits for the variables u, v, and w, and transform the function into f(u, v, w). The process of calculating the Jacobian determinant is explained, followed by the evaluation of the transformed integral. The tutorial concludes with the final result of the integral evaluation.
