Answer:
a.
[tex]Volume=15^{3}[/tex]
b.
[tex]volume=3375 in^{3}[/tex]
Step-by-step explanation:
a.
The volume of a cube of side length L is given by the formula;
[tex]Volume=l^{3}[/tex]
Our side length is given as 15 inches. Thus;
[tex]Volume=15^{3}[/tex]
b.
The power function obtained above can be simplified by the use of a calculator to obtain the volume of the cubic display case.
[tex]volume=15^{3}=3375 in^{3}[/tex]
