What are its demensions - Frigidaire FMV156DC Microwave Oven

That is an odd series of events. Microwave ovens don't have a reset button but they do have a slow blow fuse. It is no point replacing it because you have a more serious short circuit that tripped the breaker immediately. You can't work on Microwave ovens yourself as they are so dangerous inside. Also the case is fixed with special security screws. Panasonic are pretty much the best in the business and I have used many in a commercial kitchens environment. The old ones are much better made than any new one these days, so it is well worth getting it repaired. Pull it out and take in.

cubic feet is Length x width x height. so the 2.2 cubic foot would still have Length x width and therefore you would have 4,84 square feet.

I would check the cooking instructions on the side of the pizzas packaging. If microwave cooking is not listed I would not recommend cooking it in a microwave as this could make the food unsafe to eat.

But if you're short of an oven I have found a guide on barbecuing a pizza:
