Oh, dude, it's like super simple. So, to find the area of a rectangular prism, you just need to calculate the total surface area by adding up the areas of all the individual faces. It's like, you find the area of the base (length x width) and then multiply it by the height of the prism. Voilà, you've got the area of a rectangular prism!

A triangular prism has 9 edges.
Yep, you got it!
a rectangular based pyramid has got 6 edges and four faces and four vertices.
Pentagonal (not pentaginal). 7 faces 15 edges 10 vertices
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.

A rectangular prism has 12 angles. Each of the 8 vertices has 3 angles meeting at it, resulting in a total of 24 angles. However, we must divide by 2 to account for each angle being shared by two adjacent faces, giving us a final count of 12 unique angles in a rectangular prism.
