The formula to calculate the shingle weight is:
\[ SHW = LS \times WS \times 2.75 \]
Where:
The shingle weight is the total weight of a shingle based on its dimensions. It is calculated by multiplying the length and width of the shingle by a constant factor, which in this case is 2.75. This factor represents the weight per square foot of the shingle material.
Example 1:
Step 1: Multiply the length of the shingle by the width of the shingle:
\[ 3 \times 1 = 3 \]
Step 2: Multiply the result by the weight constant (2.75):
\[ 3 \times 2.75 = 8.25 \]
The Shingle Weight (SHW) is 8.25 lbs.
Example 2:
Step 1: Multiply the length of the shingle by the width of the shingle:
\[ 4 \times 2 = 8 \]
Step 2: Multiply the result by the weight constant (2.75):
\[ 8 \times 2.75 = 22 \]
The Shingle Weight (SHW) is 22 lbs.
