Cube (upper face open)<br />
<strong>Edges=</strong> <strong>12</strong><br />
<strong>Faces</strong> = 5<br />
<strong>Vertices's</strong> = 8<br />
Volume = (l) 3<br />
surface area= 6(l) 2<br />
Total surface area= 6(l) 2<br />
Volume = (l) 3<br />
surface area= 4(l) 2<br />
Total surface area= 5(l) 2<br />
Note-( Cube is a special form of cuboid having all three sides equal.)
Cylinder (solid )<br />
<strong>Edges=</strong> 2<br />
<strong>Faces</strong> = 3<br />
<strong>Vertices's</strong> = 0<br />
(Wood log)<br />
(pipe)<br />
Volume =pi (r) 2 h<br />
surface area=2pi(r)h + pi(r) 2<br />
Total surface area=<br />
2(pi)rh+2(pi)r 2<br />
These two surfaces will give surface<br />
area.<br />
All three surfaces will give total surface<br />
area.<br />
(Wire of electricity has<br />
also cylinderical shape.)
