Triple Integrals | Calculus 3 | Definite Integral

In mathematics (specifically multivariable calculus), a multiple integral is a definite integral of a function of several real variables, for instance, f(x, y) or f(x, y, z). Integrals of a function of two variables over a region (the real-number plane) are called double integrals, and integrals of a function of three variables over a region (real-number 3D space) are called triple integrals.
