SUMMARY

The discussion focuses on calculating the mass of soil in an acre that is 6 inches deep, given a bulk density of 1.2 g/cm³. The volume of half an acre is determined to be 21,780 ft³. To convert this volume into mass, the conversion factors for cubic feet to cubic centimeters and pounds to grams are utilized, specifically that 1 cubic foot equals 28,316.8466 cubic centimeters and 1 pound equals 453.59237 grams. The calculation process is outlined to facilitate accurate mass determination.

PREREQUISITES
  • Understanding of volume calculation in cubic feet
  • Knowledge of unit conversion between cubic centimeters and cubic feet
  • Familiarity with bulk density concepts
  • Basic arithmetic skills for mass calculations
NEXT STEPS
  • Research unit conversion techniques for volume and mass
  • Learn about bulk density and its applications in soil science
  • Explore soil mass calculation methods for different depths
  • Investigate the implications of soil density on agricultural practices
USEFUL FOR

Students studying soil science, agricultural engineers, and anyone involved in land management or environmental science who requires accurate soil mass calculations.

Welcome to PF.

Looks like you have a volume calculation problem.

How would you begin to convert to the units of interest?
 
the volume of a half acre is 43,560ft3*.5= 21,780ft3
21,780ft3*mass (1.2g/cm3)=?
 
Well Google says
1 cubic foot = 28 316.8466 cubic centimeters
1 pound = 453.59237 grams
