I've got a problem here: Let V be the number of corners of a 3-D object, F the number of plane faces and E the number of edges. For instance, for a cube V=8, F=6 and E=12. a) Calculate V + F - E for a cube. (done this one, easy) I have a large piece of cheese in the form of a perfect cube, and I carefully slice off small portions of cheese from every corner to expose flat, new triangular faces. The cuts are small enough so they don't interfere with each other. b) Calculate the values of V, E, F and V + F - E for the resulting object. c) You should notice something about your answers for V + F - E. By thinking about what happens when you slice a corner off a cube, explain this. +rep for the person to get the answer first. :lol:
number one no one's here to answer that right now.... number two what you're doing there is double posting, I suggest you read the rules now
You shouldn't double post. Be patient and give someone a chance to answer your question. Make sure you read the rules and understand them so you don't get banned or suspended. And for your question, all the problem gives you is pi(y) and you have to solve for y? Shouldn't there be more information given...?
Re: what is.... lol^_^...y pi well, every piece of CHEESE sliced off reveals 2 more verticies, 3 more edges and 1 more face....so, your block of cheese now has 14 faces, 24 verticies, and 36 edges...an OCTAHEDRAL! V + F - E = 2 of course, that is the general relationship of faces, verticies, and edges of solid shapes ^_^
Re: Hehe If you felt like it, I only posted two of my problems here, but I'm sure the board would be happy to help. :lol:
