How do I calculate the work done while climbing stairs?

[weasal1975]

I am working on a lab and I'm not sure how to calculate the work (done by me).

I know work = W=(F Cos theta) and Force =F= W/t

In the lab I am to walk up a set of stairs and time myself. I did this and got the following:

t=8 sec
d=6m
Mass(me)= 77kg

how do I find W?

Any pointer is greatly appreciated. I know I'm making this harder than it has to be I'm sure.

I assume that by 'weight', you mean weight in the layman sense and actually mean mass, given that your units are in kilograms. (Wow, 374kg's quite a bit)

Anyway, the work done by you (against gravity) is simply the increase in (gravitational) potential energy of your body, without having to re-derive and consider forces and direction and whatnot (which may not be very intuitive in such a scenario of climbing stairs).
