## RIGHT PRISM,Volume of Right Prism,Triangular Prism,formulas and solved example

A right prism is a solid which has two
parallel planes of same

shape and size. Also, its lateral surface are
perpendicular to its

parallel sides.

Volume of Right Prism

Volume = Area of cross-section x Distance between
parallel sides

=
Base area x height

Triangular
Prism

Volume = Base area x height

=
Triangle area x length of the solid

= ½ x
base x height x length

Total surface area = Two triangles + three rectangles

= 2 x ½ x b x h + L x
b1 + L x b2 +
L x b3

= 2 x base area + (b1 + b2 + b3) x L

= 2 base area + Perimeter of the base x Length

Volume of a Prism

Volume = Base Area x
Height

= ½ x 12 x 16 x 30

= 2880 cm3

Perimeter of the base
= 12 + 16 + 20

=
48 cm

T.S.A = 2 x Base Area
+ Perimeter of the base x height

= 2 x 96 + 48 x 30

= 1632 cm2.

Trapezoid

Volume = Base Area x
Length

= ½ x
(8 + 15) x 10 x 20

=
2300 cm3.

T.S.A = 2 x Base area
+ Perimeter of the base x height

= 1670 cm2.
