Net











F - bxh 10 x 6 = 60

S - bxh 5 x 6 = 30
T - bxh 10 x 5 = 50
TSA= 60 + 60 + 50 + 50 + 30 + 30
TSA = 280 m²

Cylinder Prism

























r = d/2
r = 8/2
r = 4

d = r²

c= pi d
c= 3.14 x 8

a= pi r²

2 (pi r²) + (pi d h)
2 (3.14 x 16) + (3.14 x 8 x 12)

TSA = 401.92 m²


Triangular prism




















bxh/2 9x8/2 = 72/2 = 36
bxh/2 9x8/2 = 72
/2 = 36
l x w 5 x 8 = 40
l x w 5 x 9 = 45
l x w 5 x 10 = 50
