Answer:
There is not enough potting soil. The gardener needs 1.875 cubic feet more potting soil.
Step-by-step explanation:
In the given scenario we need to calculate the total volume of the cubic boxes.
Cubic volume = side * side * side
Cubic volume = 1.5 * 1.5 * 1.5
Cubic volume = 3.375 cubic feet
Since there are 5 planter boxes
Total volume = 3.375 * 5 = 16.875 cubic feet
The volume of soil in the 3 bags is
Volume of soil in bags = 3 * 5 cubic feet = 15 cubic feet
So there is insufficient soil to fill the planter boxes.
The difference is
Difference = 16.875 - 15
Difference = 1.875 cubic feet of soil is short
