2. WELCOME

3. Prisms
Prisms are solids ,all but two sides are rectangles
and two sides are congruent polygons.

4. Naming a Prism
Depending on the shape of the base we
classify a prism

5. Examples of Prism
Square prism
Rectangular prism
Triangular prism

6. Square Prism
End faces are square shape and the other lateral
faces are rectangular shape.
No: of Edges= 12
No: of Faces= 6
No: of Vertices= 8

7. Rectangular Prism
All the faces are rectangular shape.
No: of Edges= 12
No: of Faces= 6
No: of Vertices= 8

8. Surface area of a
Prism
Lateral Surface Area
Total Surface Area

9. Lateral surface Area
L.S.A= base perimeter x height

10. Total Surface Area
T.S.A=Area of two end faces
+ Area of lateral face.

11. Surface area Algebraic way
for Rectangular prism
S.A=2lb+2bh+2hl
Where l= length
b= breadth
h= height

12. Surface area Algebraic way
for Square prism
S.A=2a(a+2h)
Where a= side of the square
h=height

YOU
