What is the surface area of a rectangular prism that has the base of 6, height of 3, and width of two?

Question

lgbasallote · Answer

Surface are = 2(base area) + (base perimeter x height)

now...what are your base area, perimeter and height?

anonymous · Answer

oh, well the perimeter would consist of the base of 6 and the width of 2 right? so it would come out to 16 for the perimeter, I think.

2L + 2W remember?

anonymous · Answer

yeah that's what I did haha. 6 is the length and 2 times 6 is 12. Then the width is two, which would be 4 when you times it by two. Maybe I'm just doing it wrong haha

oh yeah sorry...i was looking at the wrong values :P that's the perimeter...and the area...?

anonymous · Answer

haha, it's all good :) but eh, I'm not too sure on how to get the base area.

lgbasallote · Answer

length x width the base is a rectangle right?

anonymous · Answer

oh, yeah it is. So the area would be 12, right?

lgbasallote · Answer

yep seems right so sub those values to my equation
