Answer:
The value of x is 18 ft
Explanation:
The dimension of the box,
Length, l = x ft
Breadth, b = 4 ft
Height, h = 6 ft
The shape of box is cuboid. The volume of cuboid is lbh
Volume of cuboid (Box) = length × breadth × height
Volume of box = 432 ft³
![lbh=432](https://img.qammunity.org/2021/formulas/mathematics/high-school/9j7cjlibmthrcdhsx9y5s0re8zia436x5d.png)
![x* 4* 6=432](https://img.qammunity.org/2021/formulas/mathematics/high-school/8p52pf3g2kfo4wiiyt8t347jq1d72yi4ax.png)
![x=(432)/(24)](https://img.qammunity.org/2021/formulas/mathematics/high-school/t3pu6dj1iimpbyxkvm4zddbzzaqbmaog70.png)
![x=18](https://img.qammunity.org/2021/formulas/mathematics/high-school/n2sz6qdf1mu2rolhdsvgrhnwbfuvcxr82h.png)
hence, the value of x is 18 ft
