Calculation should be based on

• building plans or drawings
• 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 one encounter if the amount of concrete needed is over-calculated? Under-calculated?
