Question

A student conducted an experiment on plant growth that required adding about one cupful of liquid fertilizer to several plants each week. In order to accurately measure the fertilizer given to each plant, the fertilizer volume should be measured in ____A cubic meters
B milliliters
C cubic feet
D kiloliters

Answer 1

Answer:

C, Cubic feet

Explanation:

Fertiliser should be applied as cubic feet.  This allows more precise control over the area of soil. Most notably the soil is not a 2 dimensional  surface but a 3 dimensional one that extends below the earth. Although the student is pouring the fertilizer on top of the earth its is spreading in a length width and height. This should be accounted for when amount is being calculated.
