The cross-section of a prism is the same - it is the same as the shape of the two parallel "bases"; this cross-section can be any shape, not necessarily a rectangle.

Each side of a prism is rectangular, so knowing the formula for a rectangle will help you along to finding the surface area of the prism by helping you to calculate the area of the sides; however, you will still need to be able to calculate the area of the bases (unless it is given to you), for which knowing the area of a rectangle may not (usually will not) help.

It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.

What is the formula for suface area of a rectangle?

The formula for a rectangle is height x width (A=ab)Since you said surface area, I'm pretty sure that you might mean a rectangular prism. To get this, you would need to find the area of each "rectangle side". To do this, you use the first formula, using height (a), width (b), and depth (c).

How is the formula for finding the surface area of a rectangular prism helpful?

It's not.. It may be, depending why, but there isn't a set formula for it. You just use the fundamental rectangle-area formulae & string them together.


What is the formula for calculating the surface area of a prism, specifically focusing on the angle of prism?

The formula for calculating the surface area of a prism is SA 2B Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism. The angle of the prism does not directly affect the surface area calculation.


What is the volume of a rectangular prism if the surface area is 34?

To find the volume of a rectangular prism when given the surface area, we need more information than just the surface area. The surface area of a rectangular prism is calculated using the formula 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the prism, respectively. Without knowing at least one of these dimensions, we cannot determine the volume of the prism.


Is a cube is a rectangular prism?

Although there is a separate formula for it, yes, a cube is technically a rectangular prism, and you can use the rectangular prism's formula, because a rectangle is defined as a quadrilateral with four right angles, which a square is.
