Applying Construction Mathematics to Residential Material
Estimating
This book was written to assist carpentry instructors and general
contractor's in understanding common construction mathematical
calculations. Although measuring devices and calculators are
common, quick, and easy to use, they can limit your thinking
abilities. Section one of this book shows how to calculate
fractions, decimals, area, volume, and angled measurements without
the use of these tools. This section also highlights the four basic
math operations and the relationship between them.
You will also find formulas, factors, and accurate short cuts that
will save you time and money. Section two of this book shows how
materials are measured and sold using practical exercises. Example:
if you are use to calculating drywall by dividing the total square
feet by 32 then check this out a ceiling area of 200 sf will need
