## How to calculate the styrofoam needed?

Multiply the area in square feet by the result of thickness (inches) divided by 12:

**Styrofoam [ft³]**= area [ft²] * (thickness [in] / 12)

Or multiply the area in square meters by the result of thickness (centimeters) divided by 100:

**Styrofoam [m³]**= area [m²] * (thickness [cm] / 100)

**Example:**Calculate the styrofoam needed for a 100 sqft area for 12 in insulation thickness.

**Styrofoam needed [ft³]** = area [ft²] * (thickness [in] / 12)

**Styrofoam needed [ft³]** = 100 * (12 / 12)

**Styrofoam needed [ft³]** = 100 ft³
