Evaluation of Volume under surface for tpaps interpolation

I have used tpaps function to interpolate my X,Y,Z data and thus have obtained a surface. Please let me know how to evaluate volume under the surface using integral2 function. I am at present using a double summation approach and fnval function using for loops to calculate volume but it takes a lot of time.

Dear Prudhvi Peddagoni,

Thanks for your reply and sorry for the late reply.

I tried the trapz function today and was able to get the answer in much less time. Thanks a lot for your help.
