We have,
Length of a cardboard box is 18 feet
Width of cardboard box is 7 feet
Height of a cardboard box is 6 inches
The conversion from one units and another is as follows :
1 foot = 0.334 yards
18 feet = 6 yards
7 feet = 2.334 yards
1 inch = 0.0277 yards
6 inches = 0.1667 yards
Now,
Length, l = 6 yards
Width, b = 2.334 yards
Height, h = 0.1667 yards
The box in the form of cuboid. The volume of a cuboid shaped object is given by :

Plugging all the values, we get :

So, the volume of the box is
