Bookmark or Share- calculus - How do I find the maximum volume for a box when the corners ...How do I approach this question when there are the corners cut out? I understand I need to label important things with variables and find an appropriate formula, however what do I do when it comes to the corners?
- geometry - Compass-and-straightedge construction of the square root of ...For example, suppose you want to find the square root of 5. Construct a right triangle with side lengths 1 and 2. This can be done with straight edge and compass. Then the hypotenuse has length $\sqrt{5} $ (times the unit). The procedure can get more complicated.
- geometry - Why there is different inradius between Icosahedron and ...$\begingroup$ In a truncated icosahedron, the planes cutting out the pentagons are not chosen to have same distance as the inradius of underlying icosahedron. Instead, they are chosen to make the hexagons regular polygon (ie. cutting at the $\frac13$ and $\frac23$ points of edges of icosahedron). $\endgroup$ –
