Answer:
Step-by-step explanation:
oof. okay.
so basically you have to find the area of each face of this shape
so I will write each area for you just so that I can keep track of where I am.
So the top one is 2*3=6
and then the side of that is 3*1=3
and then the next stair is 3*1 =3
and then again another 3*1=3
and the top of the bottom stair is 3*1=3
the side of that last one is 2*3=6
the back of the stair thingy is 4*3=12
now the weird side is (4*2)+(3*1)+(2*1)=13
you need two of those sides so another (4*2)+(3*1)+(2*1)=13
<em>(for these ones I divided it up into three parts; one were each star begins making it appear that there is a small rectangle on top of a medium rectangle on top of a large rectangle)</em>
and the bottom is 4*3=12
so then you add them all up
6+3+3+3+3+6+12+13+13+12
that all equals 74
I hope this helps!
