Really need help

I'm really confused about the performance task my teacher gave us, we need to select an object and find its area and volume using integration and I don't know what object to use

You could use a cube. The integrals will then be very easy to evaluate.
Thanks from Maschke and Benit13

Can we also get the centroid and length of arc using integration?

Yes, but do you mean for separate objects?

This. Also, prisms, cones and cylinders are all pretty easy to integrate

Choose a cylinder and sphere. It will demonstrate Archimedes was one of the first to show volume is a limit process.

By the way, how are you associating arc length with a geometric figure? Do you want to determine the length of a side or something?
