I have asked a ton of questions on here but I am having a hard time with my engineering applied physics class, and there are no teachers that can really help because the class size is 120

Calculate the area of a rectangular wood specimen, with dimensions of 0.789 in by 0.944 in.
Now to find the area of a rectangular prism don't you have to do, W x L + L x H + L x W
I only have 2 dimensions of the rectangle? not 3.

A wood specimen was tested in compression and failed at 5.65 kips ( 1 kip = 1000lbs), calculate the failure strength in psi.
This is not the same wood specimen and don't i have to know the area of the rectangle to calculate the Psi?

specimen =/= prism

if it is not the same specimen then you certainly need some information on the area to calculate the pse
