Hello Guest! :D

 

First side: 10*5 =50 cm^2

Second side: 6*8/2=24 cm^2

Third side: 6*8/2=24 cm^2

Fourth side: 6*5=30 cm^2

Fifth side: 8*5=40 cm^2

 

Add all of these up to get the desired answer! :D

In short, the answer is 143cm2.

 

This is how I did it: 

First, we must find the surface area of every face.

 

10x5 = 50

6x8 = 48 (we can do this because both triangles are the exact same)

5x8 = 40

6x5 = 30

Now we add all this up and get 143cm2.

 

Hope it helps!

You did your work nicely, but I think you made a mistake adding the values! The correct answer would be 168 :D
