A right rectangular prism measures 11 cm by 8 cm by 3 cm. What is the surface area of the prism?
I have been learning about this in math but I kind of forget how to figure it out, can someone please help?

6 sides and each side is a rectangle. think of a box) opposite sides are the same - so these rectangles are also the same measurements
2 rectangles 11 by 8 with area of 88 sq cm each - total of 176 sq cm
2 rectangles 11 by 3 with area of 33 sq cm each - total of 66 sq cm
2 rectangles 8 by 3 with area of 24 sq cm each - total of 48 sq cm
added together 290 sq cm
