Answer: OPTION C.
Step-by-step explanation:
The volume of a cube can be calculated with the following formula:
[tex]V=s^3[/tex]
Where "s" is the length of each edge of the cube.
Solving for "s":
[tex]s=\sqrt[3]{V}[/tex]
Let's check each option to find which volume would work according to the size she needs:
A. Substitute [tex]V=216in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{216in^3}=6in[/tex]
B. Substitute [tex]V=125in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{125in^3}=5in[/tex]
C. Substitute [tex]V=64in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:
[tex]s=\sqrt[3]{64in^3}=4in[/tex]
Based on these results, we can determine that the cubes with a volume of [tex]64in^3[/tex] would work.
