How To Find Area Of Rectangular Prism?

How do u find the area of a rectangular prism?

To find the surface area of a rectangular prism, measure the length, width, and height of the prism.

Find the area of the top and bottom faces by multiplying the length and width of the prism.

Then, calculate the area of the left and right faces by multiplying the width and height.

How do you find the area of a prism?

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn’t matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.

What are two ways to find the surface area of a rectangular prism?

How to find the surface area of Rectangular Prisms:

  • Find the area of two sides (Length*Height)*2 sides.
  • Find the area of adjacent sides (Width*Height)*2 sides.
  • Find the area of ends (Length*Width)*2 ends.
  • Add the three areas together to find the surface area.
  • Example: The surface area of a rectangular prism 5 cm long, 3 cm.
