Rectangular Prism (Formula A=LxW)
Front
A=LxW
A= 10 x 3
A= 30cm2
Top
A=LxW
A= 10x5
A= 50cm2
Front
A=LxW
A=3 x 5
A= 15cm2
TSA= 50+50+30+30+15+15 = 190cm2
Cylinder (Formula= d/2=r - C=(pi) x d)
(cylinder Picture is at the top)
Top
d/2=r
50/2=r
25cm2
C=(pi) x d
C=3.14 x 50
C=157cm2
TSA= 157 + 157 + 25 + 25 = 364cm2
Triangular Prism (Formula= b x h/2 - A=L x W)
(triangular prism is at the top)
A=b x h/2
A=10 x 20/2
A=100cm2
A=L x W
A=50 x 30
A=1500cm2
TSA= 1500 + 1500 + 100 + 100 = 4700cm2
