well I'm doing a project of an icosahedron, and I have no idea what I'm doing. My icosahedron has 12 verticies 29 edges and 20 faces. I just need to know what the volume and the surface area is. Can u explain the whole equation step by step. I looked it up and it said something about 5 divide it by 3a2, I have no idea what that means. Can u also explain that. Please and thank you

There is a formula for this question. Since you know how to use a computer you could Google it. Let me google that for you (http://lmgtfy.com/?q=volume+of+a+icosahedron)
