9) A 55 pound bag of soil holds 1/2 cubic foot of soil. In order to fill a square flower box measuring 4-feet long and 1-foot high, how many bags of soil must be used?

1. 8 bags
2. 16 bags
3. 32 bags
4. 40 bags

To find the volume of the flower box you take l×w×h. Don't forget that the measurements are for a square flower box, so you can assume that if the box is 4-feet long, then it's also 4-feet wide. So 4×4×1=16 cubic feet. Each bag holds 1/2 cubic foot of soil.

¹⁶/_(1/2)  = 16 × 2 = 32.
