Microsoft Excel 2007, along with the other products in the Microsoft Office 2007 suite, introduced new file formats. The first of these (.xlsx) is defined in the Office Open XML (OOXML) specification.
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides) In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same. The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc.
To find the surface area of a right triangular prism we must use this formula: SA = wh + lw + lh + ls. The variables in this formula stand for: w = width h = height l = length s = side. w = width h = height l = length s = side. Let's put this formula to use. You can use a calculator to help.Find the surface area of this right triangular prism. Dimensions are in feet. SA = wh + lw + lh + ls SA = 5(6)+9(5)+9(6)+9(7) SA = 30+45+54+63 SA = 192 ft Here's another one. Find the surface area of this right triangular prism.
