Multiple integrals can involve two or more variables. 

Multiple integrals are used in engineering, particularly in structures and mechanics, to determine the properties of plane and solid bodies. These properties include volume, mass, center of gravity, and moment of inertia. 

Here are some types of multiple integrals:

Double integral
Used to find the surface area of a 2D figure. It can also be used to calculate the area of a region, the volume under a surface, and the average value of a function of two variables over a rectangular region. The general form of a double integral is ∫ ∫ f(x,y) dx dy, where f(x,y) is the function being integrated and x and y are the variables of integration.

Triple integral
Used to find the volume of a -dimensional object in a -D space. The total volume of a closed region in space can be written as V = ∭ Ddv which is equal to V = ∭ D d x d y d z.
