To figure out the surface area of a reactangular prism you have to multiply length x width and then multiply that by how many faces it has, to figure out volume you multiply the length x width x height of the prism and than you will find your answer!!!!!
Length x width (: trust me!*
If the room is rectangular, the area is the product of its length and width.
It is length * width.
Rectangular Prism surface area formula is Area = 2 (wh + lw + lh) (Length x width of a side) x 2 + (length x width of perpendicular side) x 2 + (length x width of end) x 2 = surface area of a rectangular prism
Multiply length x width.
The formula for the surface area of a rectangular solid is = 2lw + 2lh + 2wh 2(length x width)+2(length x height)+2(width x height)
The area does not provide sufficient information to determine the length, width and height.
if length and width are doubled then the volume should mulitiply by 8
You need three measures of length to determine the surface area - the length, width and height.
you multiply the length times width times height.
In the absence of any further information, multiply the length by the width

-- Picture the rectangular prism in your mind, or sketch it on paper.-- Label the edges with the dimensions.-- Notice that . . .- The area of the top and bottom faces is (length x width), and there are two of them.- The area of the left and right sides is (length x height), and there are two of them.- The area of the front and back ends is (width x height), and there are two of them.-- So the total surface area of the rectangular prism is(2) x [ (length x width) + (length x height) + (width x height) ] .
