1. Volume of Prisms
1. Volume – the number of cubic units
needed to fill a given space.
2. Cubic unit – space occupied by a cube
of unit measure.
Ex.1. V = Bh
8 in V =(b h) h
6 in
V = 12(6)(8)
12 in V = 576 in³
V = Area of base x height of the prism

2. Volume of Prisms
Ex.2.
b = 2.5 in
h = 2.5 in
5 in h = 5 in
V = Area of base x Height
2.5 in V = Bh
2.5 in
V = bhh
V = 2.5(2.5)(5)
V = 31.25 in³

3. Ex.3. Find the volume of the triangular prism
V = Area of base x height
10 in
V=Bh
8 in 14 in
h = 14 in
6 in
bxh 6x8
8 in Area of base B = 2 = 2
6 in = 24 in²
V=Bh
= 24 (14) = 336 in³

4. 10 in What is the relationship
between the volume of a
triangular prism and a
8 in 14 in rectangular prism?
6 in So, we can use the same
formula, but divide it by 2.
V=
bhh
2
(8)(6)(14)
V=
2
V = 336 cubic inches
