Question

To find volume _________________ can be used.

(a) single integration

(b) double integration

(c) triple integration

(d) double & triple integration

I had been asked this question during an interview for a job.

Query is from Volume Integrals topic in chapter Vector Integral Calculus of Engineering Mathematics

Answer 1

Correct option is (d) double & triple integration

The best explanation: To find volume, triple integration should be used and proper limits should be given for each variable.

But volume integration can also be done using double integration by using 1D equation of the 3D object as the function.
