The formula to calculate the Plate Cost (PC) is:
\[ PC = L \times W \times T \times CPSI \]
Where:
Let's say the length (L) is 10 inches, the width (W) is 5 inches, the thickness (T) is 0.5 inches, and the cost per cubic inch (CPSI) is $2. Using the formula:
\[ PC = 10 \times 5 \times 0.5 \times 2 = 50 \]
So, the Plate Cost (PC) is $50.
