Look at the front face.... it has 2 x 6 squares = 12 squares .....the BACK face (the one you can't see) has the same

so far 2 x 12 square

Now look at the side face. It has 2 x 4 squares = 8 squares .... the LEFT face (you can't see) does too...

add 2 x 8 squares

Now look at the TOP face. It has 6 x4 squares so does the BOTTOM face (you can't see)

add 2 * 6 x 4

Add up the Reds.....what do you get????

rectangular solid area =2[LW + LH + WH]

=2[6*4 + 6*2 + 4*2]

=2[24 + 12 + 8 ]

=2 x [ 44 ]

**= 88 Square Units**.

Obviously, two others have already posted their own solution, but I put in a solution earlier at https://web2.0calc.com/questions/helppppp_16#r1

Given that the forum title of this question is "i still dont get it," I assume that you were confused with my solution. You are always strongly encouraged to request for clarification. It is detrimental to you to pretend as if you understand.

Is there a particular section that confused you?

Do you understand what "surface area" means?

Is there a particular section where you would like more detail?
