We have two equations of the given that will be useful for the answer to this question:
• Formula for the area of a triangle, (, A ,), in which ,b ,represents the base of the triangle and ,h ,the height:

• Formula of the volume of the prism ,(, V ,), in which ,B ,represents the area of the base, and ,h ,which represents the height of the prism (and our unknown variable):

Procedure:
0. Finding ,A:



Therefore, based on this result, we can replace the value in the volume formula to get h.
2. Replacing values:


3. Isolating for h:

Answer:
![h=100\operatorname{mm}]()
