Given:
a.) A triangular prism has a base area of 43 square meters.
b.) Its volume is 645 cubic meters.
Recall: Formula in getting the volume of a triangular prism.
[tex]\text{ Volume = }BH[/tex]Where,
B = Base area of the prism.
H = Height of the prism.
Let's now determine the area of the prism:
[tex]\text{ Volume = BH}[/tex][tex]\begin{gathered} \text{ 645 = (43)H} \\ \text{ }\frac{\text{645}}{43}\text{ = H} \\ 15\text{ = H} \end{gathered}[/tex]Therefore, the height of the prism is 15 meters.
