Write and simplify an expression for the surface area of a rectangular prism with a height of h yards, a length of 2.6 yards, and a width of 3.5 yards. What is the surface area if the height is 4 yards?


SA= _+ _ h

The surface area is yd^2

What is the formula for SA of rectangular prism whose length is L units, width is W units and it is H unit tall?
 
length is 2.6 yards
width is 3.5 yards
height is 4 yards
I know the surface area is 67 yd^2
I just don't understand the first question
SA= _____ + ______h

what do I put in the blanks??

As posted, I do not understand it either!

Please post the complete problem as it was presented to you.

I had already answered your question. You don't know I need someone else to help me.

I do not see formula (for SA) in any of your responses. I don't think you answered my question:

@Helpmepleasewthmath : Why don't you answer Sub's question? If you do you will wind up with (something) + (something else)* h. Then you will see what numbers to put in where. With your attitude "if you don't know I need someone else" I wouldn't be surprised if nobody answered you.
