Kaitlyn is wrapping a present shaped like a rectangular prism with a length of 3.1 inches, width of 20.8 inches, and height of 6.2 inches. What is the total surface area of the present? Round to the nearest whole number.
The area of the two bases = 2(3.1 inches)(20.8 inches)
And the area of the sides is 2* [ (3.1 inches)(6.2 inches) + (20.8 inches)(6.2 inches) ]
I'll let you finish this one....
