here: :)

I did the work, and basically i solved for the area of the faces and then multiplied that by two to get the total surface area of the faces. Then I added in the areas of the sides connecting the two faces:

just as a referral: the formulas to find the faces are as follows:

rectangle: length times width

circle: pi x r^2

trapezoid: h(base1 + base2)

and triangle: (b x h)/2
