How do i find the lateral area and the surface area of a rectangular prism

with the height of 8.5"
the width 4"
the depth 3.25"
I don't want you to do it for me i want to know what formula or how i start to solve for those two things please

    ok i found how to do the surface area but i still don't know what to use for the lateral area

  • math -

    i don't get lateral area either

  • math -

    This is from the above site:

    "The lateral area L (area of the vertical sides only) of any right prism is equal to the perimeter of the base times the height of the prism (L = Ph)."

    If the perimeter of the base is 10 inches and the height is 3 inches, then the lateral area is 30 inches.

  • math -

    the lateral area of a solid is the surface area with the base excluded.


    So if it says to find the surface area of a cone you would include the circle, but if you are to find the lateral area of a cone you would find only the top part surface.
