Triple Integral Calculator with Steps Free

Triple integrals are used in physics and engineering to calculate quantities like mass, charge, or probability over three-dimensional volumes. This calculator provides step-by-step solutions for evaluating triple integrals in Cartesian coordinates.

What is a Triple Integral?

A triple integral extends the concept of double integration to three dimensions. It calculates the volume under a surface bounded by three variables. The general form is:

∫∫∫ f(x,y,z) dV = ∫∫∫ f(x,y,z) dx dy dz

Triple integrals are essential in physics for calculating mass distributions, electric charge, and other physical quantities over three-dimensional regions.

Formula Used

The triple integral is evaluated using the standard iterative approach:

∫[a][b] ∫[c][d] ∫[e][f] f(x,y,z) dz dy dx

The calculator performs this calculation numerically for most functions. For exact solutions, symbolic computation is recommended.

Worked Example

Calculate the volume under the plane z = 2x + 3y from x=0 to 2, y=0 to 1, z=0 to 2x+3y.

∫[0][2] ∫[0][1] ∫[0][2x+3y] 1 dz dy dx

The calculator would evaluate this as approximately 4.00 cubic units.
