Answer to Question #22379 in Mechanics | Relativity for Lee

Question

I am trying to calculate the center of mass on a project I am building but I'm kind of lost on how to figure it out.
The overall length is 159.5" and width is 52", overall weight is 90lbs with a weight of 175lbs 54" from the left and 80lbs 82.5" from left.
Can you help me figure this out?
