1. The problem statement, all variables and given/known data A cubical box has been constructed from uniform metal plate of negligible thickness. The box is open at the top and has edge length L = 97 cm. Find (a) the x coordinate, (b) the y coordinate, and (c) the z coordinate of the center of mass of the box. 2. Relevant equations rcom=(1/M)sum(mi*ri) 3. The attempt at a solution I could not figure out what to do with a three dimensional object since we are not given a mass.
