Answer :
Answer
The volume of right rectangular prism 10 cubic inch.
Step-by-step explanation:
The volume of cube[tex]=a^{3}[/tex]
each edge of cube[tex]=\frac{1}{2}[/tex] inch
so,
the volume of cube[tex]=\left [ \frac{1}{2} \right ]^{^{3}}[/tex]
one cube of volume [tex]=\frac{1}{8}[/tex] cubic inch.
[tex]80[/tex] cube of volume[tex]=80\times\frac{1}{8}=10[/tex] cubic inch
so the volume of rectangular prisme equal to volume of 80 cube.
