Question from Mary: 50 cubic yards of dirt is allowed. 16 feet of width and 1 foot of depth. How far can can you cover in length? in feet, yards or miles? Thank you. |
Hi Mary,
First off, you need all of your information in the same units: 1 cubic yard is 27 cubic feet so the volume of dirt is 27 × 50 cubic feet = 1350 cubic feet. I'm not sure what type of shape this is for but I'll assume
Volume = length × width × depth
1350 ft3 = length × 16 ft × 1 ft, and hence
length = 1350/16 ft
For the other answers you will need to convert the units from feet to yards and miles.
