## Triple integrals 3 (video)

If the solid W is a cube defined by a ≤ x ≤ b, c ≤ y ≤ d, and p ≤ z ≤ q, then we can easily write the triple integral as an iterated integral. We could first integrate x from a to b, then integrate y from c to d, and finally integrate z from p to q , ∭

## 15.4: Triple Integrals

But triple integrals can be used to 1) find volume, just like the double integral, and to 2) find mass, when the volume of the region we’re interested in has variable density. In this

## Triple Integrals

The notation for the general triple integrals is, ∭ E f (x,y,z) dV ∭ E f ( x, y, z) d V Let’s start simple by integrating over the box, B = [a,b]×[c,d]×[r,s] B = [ a, b] × [ c, d] × [ r, s] Note
