A solid has $40$ faces and $60$ edges. Find the number of vertices.

Draw the net of a regular hexahedron with side $2 \mathrm{cm}$.
 

Count the number of cubes in the following shape.


 

Count the number of cubes in the following Shapes.


 

If a length of $100 \mathrm{m}$ is represented in map by $1 \mathrm{cm},$ then find the actual distance corresponding to $13 \mathrm{cm}$.

The actual width of a store room is $320 \mathrm{cm}$. If the scale chosen to make its drawing is $1:4$, then the width of the room in the drawing is $k \mathrm{cm}$, then write the value of $k$.

The scale on a map is $1 \mathrm{m} : 9 \mathrm{m}.$ Find the distance on the map for an actual distance of $63 \mathrm{m}$. 

A solid has $20$ faces and double edges to its faces. Find the number of vertices.
