You look at the vertex.and depending on what it looks like
-1/6 + 2/3 (9-3/4)-1/2
= -1/6 + 2/3 (33/4) -1/2
= -1/6 + 11/2 - 1/2
= 16/3 - 1/2
= 29/3
1st letter can be any of 5 letters
2nd letter can be 5-1 any of 4 letters
5*4 = 20
there are 20 possible passwords
Lateral surface area is the area that can be seen from the solid, while total surface area includes the region that can't be seen on the solid. For example in cylinder: LSA = pi*r*l while, TSA = 2pi*r^2 + pi*r*l .
