triangular prism
Both are prisms. A prism is a 3D shape which has a uniform cross section, so anywhere along it's length where you take a slice you always see the same shape. To say which prism you mean we add the name of this cross section 'triangular prism', 'hexagonal prism' etc. We have a special name for a circular prism - a cylinder. Also, a rectangular prism is a cuboid.
Not actually, People say that for fun. People say that "1+1=" is a window because the numbers and symbols can make a window like shape out of them. . ___ .1 + 1 Do you see it?? ..----- . ___ .| + | The plus sign is the cross section of the window. .------
There is no 2D shape that makes a sphere, since a sphere is 3D by definition. The closest thing to a 2D sphere is a circle.
You will see a rectangle

The cross section is useful as it cuts across any type of shape. This is useful for architects who will be able to see the finer details of a structure.
Imagine that you wanted to cut a globe or a sphere exactly in half. When you looked at the cut you would see an exact circle on both pieces. This area would be the cross-section. You could work out the area of this cross-section by using A = Pi X r squared. But be careful. Don't assume that the cross sectional area is the same no matter where you cut. If you cut the globe at some other point, say near to the edge, the cross-section (the circular area that you would see) would be a lot smaller. You would come across a uniform cross-section if you cut a cable. No matter where you cut the cable the cross-section should be roughly the same. Also cross section doesn't have to be circular. The cross-section you get really depends on the original shape you are dealing with. If you cut a cube in half, you would get a square cross-section. So I guess you could imagine the term as applying to cutting across (hence cross) something to reveal 2 sections (hence section).
What can you see in the Cross-Section View that you can’t see in the Map View?

a cross section applies to anything...it is a way of looking at something inside. imagine cutting through a pump (for example) and then looking perpindicular at it, like holding it out in your hands like binoculars, the shape that you see (a circle probably in this case) is called the cross sestion.

yes!!

If you follow the link below you will see that another name is a 'cuboid' http://www.mathsteacher.com.au/year7/ch09_polygons/06_polyhedra/prism.htm#prism
