Hi I'm Alexander T. 2 ° F . Today
1, we have done a quick calculation of areas and perimeters. The 2 nd we discussed the problem of the week ( the bear, which many have been "pissed" ). The 3, the teacher has explained the latest volumes formula, that of the sphere with respect to the cylinder. Finally we h exercise echo with the new formula and sent us home page 27/29a/30/34/36 216 exercises.
The other day a friend of mine gave me a solid figure and do not know if I have a name or not and how many sides has a polygon.

Written by Professor: This polyhedron has proposed to us by Alejandro outgoing angles (convex) and incoming angles (concave). We see that their faces are squares of 4 colors blue and isosceles triangles. White faces formed by two triangles are actually square. With those pictured and reasoning by symmetry, plus the help of Euler, we know how many of each type are expensive, how many vertices and edges. Who is the first or the first to tell us?
