We find objects in the shape of a parallelepiped everywhere - these are most buildings, and various boxes, and bricks, and sugar cubes. This form is taken as the basis for the production of many cars. In our apartments, we are surrounded by parallelepipeds of furniture!
It is necessary
Thick paper or cardboard, pencil, ruler, scissors, glue
Take paper or cardboard - large demo models of parallelepipeds are glued from cardboard, and small ones from thick paper. On a piece of cardboard, use a ruler and a pencil to sketch out the model of the size you require.
Draw the model so that the longest side only needs to be glued once. Do not forget about the sides, draw them one on each side. Carefully check all dimensions and angles so that there are no distortions when gluing, and the model has the correct shape. Draw the fold lines with a dotted line.
Make glue allowances about one centimeter. Cut the corners of the allowances to the main pattern so that they do not interfere with the gluing of the model. Cut out the reamer and, if it is paper, bend it along the fold lines, and if your model is made of cardboard, then carefully cut the cardboard along the fold lines with a knife along the ruler and bend it in the opposite direction.
Coat the folded strips of paper (allowances) with glue and glue from the inside to the edges of the corresponding sides, press and iron with a ruler or eraser. Glue the five sides of the parallelepiped in this way. Wait until the glue is completely dry, and the future parallelepiped acquires the necessary rigidity, then glue the last sixth side. Press it down on top with a light board or pencil case.
If you glued a cardboard model of a parallelepiped, then for a more presentable look, cover it on top with white or colored paper. To do this, make the same unfolded paper and stick it onto a cardboard box. Allow the glue to dry completely before using the model. Glue several models of geometric shapes, paint with acrylic paints in different colors or draw drawings or an ornament on them - in this form, your crafts can serve as a decorative interior decoration!
