How to figure square feet of walk way

To calculate what you need multiple all steps

To calculate what you need, multiply the walkway's width and length to find the square footage.

Step-by-step explanation:

To calculate what you need, multiply the walkway's width and length to find the square footage; for example a 4-foot-wide, 50-foot-long walkway covers 200 square feet. Next, factor in the thickness: 4 inches converts to 0.33 feet; multiply this by the square footage to find the cubic feet: 200 x 0.33 = 66 cubic feet.
