Calculate the surface area of the solid. do not include units of measure.

Hey there!

Surface area is for three dimension figures, and measures the area and how much space and as aforementioned area is in the object. This shape is a rectangular prism, so the surface area formula is:

2(lw+wh+lh)

Surface area is just an adding of all of the areas of the sides. It's times two because just the parentheses cover half the object. Plug in values:

A = 2(6*17 + 6*9 + 17*9) =
2(6)(17) + 2(6)(9) + 2(17)(9) =
204 + 108 + 306 =
618

Hope this helps!
