Answer:

3.75 feet.

Step-by-step explanation:

Given:

The volume of a right octagonal prism is 30 cubic feet.

The area of the octagonal base is 8 square feet.

Question asked:

What is the height of the prism ?

Solution:

As we know:

 $Volume\ of \ octagonal-prism=base\ area\times height$

$30=8\times height\\ \\ By\ dividing\ both\ sides \ by\ 8\\ \\ \frac{30}{8} =\frac{8}{8} \times height\\ \\ 3.75=height$

Therefore, height of the prism is 3.75 feet.
