Triangular based pyramid with no bottom. That is, if you meant 3-D shapes, presumably?
A cube.
They are alike because they are both 3-D shapes
There are different formulae for different shapes and these vary in complexity.
a opened cube is the shapes net and it is 2-D if it is closed then it is a 3 dimensional shape.
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
There are infinitely many 3-D shapes so it is not possible to name them individually.
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
If you can make it just by cutting it out of a piece of paper, it's 2-d. If you can make it by carving a block of wood, it's 3-d. 2-d shapes have length and width, but not height. 3-d shapes have length, width, and height. Here's an example: a rectangle might be 2" long and 5" wide, but those are the only numbers you use, so it's a 2-d shape. A house is 60' long, 25' wide, and 10' tall, so it's 3-d.
-hedra.
Polyhedrons

There are infinitely many such shapes. There are infinitely many such shapes. There are infinitely many such shapes. There are infinitely many such shapes.
No because isosceles triangles are 2 dimensional shapes.
circles and ovals In 3-D, spheres and oblate spheroids
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
4D includes smell.
