Find the area of the field by multiplying the length by the width:

360 x 160 = 57, 600 square feet.

Divide total area by 1000 and multiply by 8 to find how many pounds are needed:

57,600 / 1000 = 57.6 x 8 = 460.8 total pounds of fertilizer is needed.

Divide total by 50 to get the number of bags needed:

460.8 / 50 = 9.22 bags, round up to 10 .

You would need 10 bags.
