Dr. Sanjeev Verma and R.K. Tyagi Solutions for Chapter: Representation of 3D in 2D, Exercise 2: ASSIGNMENT 9.2

Look at the figure at right and answer the following:

Let $EFGH$ be the base, then name the line segment which can be considered as the height of the cuboid.

How many vertices and edges do the following figure have?

How many vertices and edges do the following figures have?

Name any four objects from your environment, which have the form of a cuboid

Name any four objects from your environment, which have the form of cylinder

Verify Euler's formula after counting the total number of vertices, edges and faces in the figure given at right.

Draw two nets of a cuboid of dimension $5 \mathrm{cm}\times 5 \mathrm{cm}\times 1 \mathrm{cm}$.

Draw the net of a cube and place the numbers $1, 2, 3, 4, 5$ and $6$ so that opposite faces have the sum as $7$.
