Answer :

What is a triangular prism?
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is a name given to this novel 3D object.
We know,
Volume = (√3/4)a²×h
We have:
h = 25 cm
a = 3 cm
Volume = (√3/4)3²×25
Volume = 225√3/4 cubic cm
or
Volume = 97.42 square cm
Thus, the volume of the prism whose length is 25cm and whose cross-section is an equilateral triangle is 225√3/4 cubic cm or 97.42 square cm.
