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
