Cubic size of Goldstar MA-1160MW

generally speaking you buy and OTR microwave by width, i.e., 30" wide is the standard width of all most all OTR . so any 30' wide microwave will fit. when talking about cubic feet, they usually are talking about the interior capacity of the microwave. but if you really want to know cubic feet of above dimensions, then multiply all three together and divide by 1728. (4.036 cuft)

The Goldstar MA-960M (also 961M and 963M) is 850W, 0.9 Cu.ft. The MA-1080M (1081M and 1083M) is 850W, 1.0 Cu.ft; MA-1280M (1281M and 1283M) is 900W, 1.2 Cu.ft; MA-1523M is 900W, 1.5 Cu.ft. Source: Technical Specifications listed in original user manual for MA-960M.

CFM would be "cubic feet per minute", which is a measure of how much air the cooling or vent fan pushes. That specification is not listed in the Goldstar / LG owner's manuals or service manuals I've seen.
If you might mean the cubic feet (CF) size of the cooking cavity, the M1500-series have 1.5CF capacities.

That sheet is called the Waveguide Cover and its function is to stop debris and food entering the aerial and magnetron.
Replacement is essential and must be made of mica.
It can be purchased from a dealer at a reasonable cost.
Google the manufacturer and find a dealer.
Hope that helps.
