Given
Original cans
Height of 6 inches
Diameter of 4 inches
New boxes
2 inches deep
4 inches wide
Same volume
Procedure
Now let's calculate the volume of the soup cans.
[tex]\begin{gathered} V=\pi r^2h \\ V=\pi(2)^2(6) \\ V=75.36\text{ cubic inches} \end{gathered}[/tex]Now let's calculate the volume of the boxes
[tex]\begin{gathered} V=2\cdot4\cdot h \\ V=8h \end{gathered}[/tex]Now we must equal the volume of the cans and then calculate the height.
[tex]\begin{gathered} 75.36=8h \\ h=\frac{75.36}{8} \\ h=9.42\text{ inches} \end{gathered}[/tex]The height of the boxes must be equal to 9.42 inches.
