a triangular prism has a base that is right a triangle. the volume of the prism is 100cm cubic how do find the height and base

Since you have not provided all the elements to determine
the height and the base of the prism, I'll give some indications on how to draw a
prism.

The first step is to draw the base, that is a
triangle. Draw the vertex of the triangle pointing on
you.

The next step is draw a perpendicular on each vertex
of triangle. The perpendicular lines must have the same
length.

Now, you'll have to join the upper endpoints of
these 3 perpendiculars and the triangular prism is
ready.

Now, for finding the lengths of height and base, all
we know is that the volume is of 100 cm^3.

The volume of
the triangular prism is:

V =
A*h

A is the area of the triangular base. If the base is a
right angle triangle, the area is the product of the legs divided by
2.

h represents the height of the
prism.

You can notice that there are more
unknowns than given data, therefore the lengths of the height and base cannot be
evaluated under these circumstances.
