Surface Area Growing Post
So for this post we have to show what we know and learned about triangular prisms, rectangular prism & cylinders.
A=30x20 A=600m squared
A=200m squared Total Surface area= 300x2+200x2+600x2
Total Surface area= 2200m squared
Area of a Prism LxW C=D(Pi)
C=12xPi C=37.68m2 A=D/2
A=12/2 A=6 A=6x6xPi A=113.04m2
Total Surface Area= 2788.32+113.04x2 Total Surface Area= 3014.4m2
A=100x2 A=200m squared A=BxH/2 A=100x8/2 A=400m squared TSA= 400x2+200+200 TSA=1200
Tell me what I did wrong or good.
