**Mechanical Engineering Stresses**

I am really struggling with the following problem:

A rectangular tube with no given length has the dimensions shown in the diagram (within the attachment). Find the maximum tensile and compressive stresses that such a section will experience due to a bending moment of 20KNm.

The attachment should be included if I've done it right.

I think i should be using "Second moments of area", but I'm not sure some clarification and possibly the formula would be gratefully received.

Thank you

Chris
