Which of the following net diagrams can be used for the above-shown pyramid (rectangular base)?

Consider the net figure of a rectangular pyramid:

Let the number of edges be E and number of vertices be V (in the 2-D figure: take edges as the intersection lines and vertices as intersection points of the lines).Then the value of E + V is 24. True/False?

Consider the figure:

Let the number of faces be F, the number of edges be E and number of vertices be V. Then find the value of F + E + V.

The above figure is a net for a dice.

If two cubes of dimensions 3 cm by 3 cm by 3 cm are placed side by side, then the resulting dimension of the cuboid is length (l), breadth (b) and height (h). Find the value of l+b+h (in cm).​

The sketches which give an idea of how a figure looks like, when seen from the front (the exact dimensions need not be the same) are called:

Two dice are placed side by side as shown in the figure. What would be the sum of the numbers which are on the opposite faces of 5 and 6 respectively?

The sketches drawn on a sheet which is divided into small equilateral triangles are called:

Consider the figure of an opened die given below:

What is the value of B?

The front-view and top-view of a cube are the same.
