Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
Well a triangle equals 180 degrees so if you already have 90 then you would need the other 90. By looking at the triangle I would say y=45. I hope I helped! :)
