Parts of Cube, Cuboid, Pyramid and Prism

Is it possible to create a polyhedron with $8$ faces, $12$ vertices and $18$ edges? Justify.

To which of the given solids is Euler's formula applicable?

The total surface area of cube 'A' is $128 \mathrm{cm}²$ more than its curved surface area. If each edge of cube 'B' is $75\%$ more than that of cube 'A', then find the sum of the curved surface area and the total surface area of cube 'B'

The side faces of a pyramid are always:

Explain why this shape is not a prism.

This $3\mathrm{D}$ shape is a:

The side faces of a prism are 

A pyramid has 

Find the volume of a triangular pyramid when the base area is $12 c{m}^2$ and height is $6 cm$?

Find the volume of a triangular pyramid when the base area is $9 c{m}^2$ and height is $4 cm$?

If $\sqrt{k}$ is the height of a square pyramid of base edge $14 cm$ and slant height $12 cm$, then find the value of $k$. 

Make a triangular pyramid that has an equilateral triangle for a base and three isosceles triangles for its side faces. Begin by drawing a net on some grid paper.

For some shapes, the net does not always use the corners of the squares but the grid still makes the drawing easier. This is the start of a net that would make a triangular prism.

Is it possible to make a triangular prism in which the two triangular faces are isosceles triangles?

If $k\sqrt{7}$ is the height of a square pyramid of base edge $12 cm$ and slant height $10 cm$, then find the value of $k$. 

For some shapes, the net does not always use the corners of the squares but the grid still makes the drawing easier. This is the start of a net that would make a triangular prism.

Finish the net and make the triangular prism.

For some shapes, the net does not always use the corners of the squares but the grid still makes the drawing easier. This is the start of a net that would make a triangular prism.

What do you notice about the length of the sides of the triangle?

Draw a prism, name it and also describe the prism.
