Calculation should be based on
- building plans or drawings
- use of the formula for determining concrete volume
- concrete strength (pounds per square inch)
- cost per cubic yard of concrete needed
- additional fees (e.g., delivery, unload time).
Process/Skill Questions:
- What information is needed to calculate the quantity and cost of materials?
- What is the standard unit of measurement for concrete?
- What is the formula for calculating concrete volume?
- What issues might you encounter if you over-calculate the amount of concrete needed? Under-calculate?
