Parallelepiped

parallelepiped1 1
A parallelepiped is a polyhedron with six faces.
 
For a rectangular parallelepiped, all six faces are rectangles.
For an arbitrary parallelepiped, all six faces of the parallelogram.

How to understand and remember the word parallelepiped?
Divide it into two parts:
           paralle - means parallel (Greek),
             pypid - means the plane (Greek).
Or a geometric body bounded by parallel planes.

To understand what kind of a geometric solid, an ordinary brick is best suited.
This is a real rectangular box.

Types of parallelepipeds

All types of parallelepipeds can be divided into rectangular and oblique.

How to make a rectangular parallelepiped?

To assemble the parallelepiped, you will need to print the unfolding on a regular A4 sheet. Download the net.
For printing, you can use both white and colored paper.

If you are using a color printer, then we suggest making a parallelepiped where the parallel faces have the same colors.

1. Cut out the parallelepiped net along the marked lines.parallelepiped razvertkaf 1
2. On the flaps indicated sequence gluing.
Sticking central flap we get:parallelepipedf 2
3. Glue the parts in the gluing place number 2 and number 3    parallelepipedf 3
4. Get the finished model of a rectangular parallelepiped:parallelepipedf 4

Difficulty memorizing

There are cases when the word parallelepiped is confused with the word parallelogram.
And, indeed, these words are consonant.
 
What is the difference between parallelepiped and parallelogram?
A parallelogram is a quadrangle whose opposite sides are parallel, that is, they lie on parallel straight lines. Special cases of the parallelogram are rectangle, square and rhombus.
A parallelogram is a flat figure.
A parallelepiped is a volume solid, all faces of which are parallelograms.
A parallelepiped is a polyhedron with six faces and a parallelogram each.

Joke:
"Sometimes, careless students try to calculate how many grams are in a parallelogram and how many parallel pypids are in a parallelepiped!"
