To find the volume of the rectangular prism, we need to multiply the length, width, and height:
Volume = length x width x height
First, we need to convert the length to yards and fractions of yards, since the other dimensions are already given in yards:
14 1/5 yards = 14.2 yards
Now we can plug in the values and calculate the volume:
Volume = 14.2 yards x 7 yards x 8 yards
Volume = 795.2 cubic yards
Therefore, the volume of the rectangular prism is 795 1/5 cubic yards.
