What are some advantages & disadvantages of a rectangular prism?

Shippers can handle rectangular prism-shaped packages of size and weight within their specifications. Many material-handling systems are designed to work well with rectangular prism shapes. (Not so much for packages too small, too large, too heavy, or of odd aspect ratio or weight distribution.)

Depending on the package contents, much space may be wasted, or much packing material may be required. Some rectangular prism shapes (and some package materials or content) don't stack well, so may require more space for shipping or storage.

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?

yes
