The figure below is a right rectangle prism. Which expression represents the volume of the prism ?

Answer:
The expression that represent the volume of the prism is [tex]\frac{1}{2}x^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the prism is equal to
[tex]V=LWH[/tex]
In this problem we have
[tex]L=x\ units[/tex]
[tex]W=x\ units[/tex]
[tex]H=(1/2)x\ units[/tex]
substitute
[tex]V=(x)(x)(1/2)x=\frac{1}{2}x^{3}\ units^{3}[/tex]
