To find the surface area of a prism, we need to add up the areas of all the faces.
A rectangular prism has two congruent rectangular bases and four rectangular lateral faces. The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism.
Given that H=9, L=8, and B=16, we can plug these values into the formula and get:
Surface Area = 2(8 x 16) + 2(8 x 9) + 2(9 x 16)
Surface Area = 256 + 144 + 288
Surface Area = 688
Therefore, the surface area of the prism is 688 square units.
