Prism
Finding the volume of a general prism is a matter of multiplying the area of the
base times the height of the prism:
Volume
g
eneral prism
= A x H
Identify the variables:
A = Area of the base
H = Height of the prism
The formula for the area of the base of the
prism depends upon the shape
of the base.
Rectangular Prism
Volume
rectangular prism
= A x H
= (l x w) x H
Square Prism
Volume
square prism
= A x H
= (s x s) x H
Identify the variables:
A = Area of the square base
H = Height of the prism
s = Length of the side
Triangular Prism
Volume
triangular prism
= A x H
= (
1
/
2
b x h) x H
Identify the variables:
A = Area of the triangle base (
1
/
2
b x h)
h = Altitude, or height, of the triangle
H = Height of the prism
