Google Earth has various layers and red squares/rectanguar boxes are typically coming from the Photos layer. In most cases they are user-contributed photos submitted to Panoramio. Red boxes are 360° panorama photos from 360cities.
If you open the Layers panel you'll probably see the Photos layer checked, which you can uncheck to hide the boxes. Likewise, the Places layer also shows various small colored icons (e.g. gyms, churches, art galleries, etc.) throughout the map.
They aren't related to lunch boxes in any way. Except the structure of a lunch box, which is rectangular or square, is similar to the body structure of a bovine.

Rectangular prisms are efficient shapes for packing into boxes from shipping.
Most, if not all, of them.
Because if they were such shapes as triangles, it would be hard to use up the extra volume area since most object shapes aren't shaped like wedges, you would have unused space. Keep in mind there are rectangular boxes too.
Depends on the shape of the 400 square foot area, and how you are using the boxes to cover it. The area of one face of a 20 inch cube is 400 square inches. There are 144 square inches in a square foot. So if the area to be covered is rectangular, its the sides are multiples of 20 inches, you could place 144 of the boxes on that rectangle to cover it. If you are talking about cutting the boxes open and using all 6 faces, that's another story. 1/6 of 144 is 24, so 24 boxes opened up have a total area of 400 square feet, but unless you are allowed to cut the boxes further into 20 inch squares, it might be difficult to get them to fit together to cover any reasonably shaped 400 square foot area.
Go on google and tipe in cube on images. The image that comes up is a cube.
Shoe boxes, CD cases, books.
Examples of rectangular solids include shoeboxes, shipping boxes, and refrigerators. These objects have six faces that are rectangles, and all their edges are right angles.
About five (4.975) such boxes.
because they fit in a larger box for transport and the boxes form a stronger structure for added crush resistence.
If you buy 18 boxes you will have enough, plus a few extra. 18 boxes will cover just over 434 square feet.
