Example Question #1 : How To Find The Surface Area Of A Prism
The above diagram shows a rectangular solid. The shaded side is a square. In terms of 
A square has four sides of equal length, as seen in the diagram below.
All six sides are rectangles, so their areas are equal to the products of their dimensions:
Top, bottom, front, back (four surfaces):
Left, right (two surfaces):
The total surface area:
Example Question #5 : Finding Volume Of A Rectangular Prism
A rectangular prism has a width of 3 inches, a length of 6 inches, and a height triple its length. Find the volume of the prism.
A rectangular prism has a width of 3 inches, a length of 6 inches, and a height triple its length. Find the volume of the prism.
Find the volume of a rectangular prism via the following:
Where l, w, and h are the length width and height, respectively.
We know our length and width, and we are told that our height is triple the length, so...
Now that we have all our measurements, plug them in and solve:
