Converting inches to feet by dividing by 12, the missing value in the table is found to be 216 inches, indicating a corresponding actual length of 30 feet for 10 inches on the drawing.
You need to convert inches to feet. There are 12 inches in one foot, so you can divide the length on the drawing by 12 to get the actual length in feet. For example, 2 inches on the drawing is equal to 2 / 12 = 0.1666666667 feet in reality.
To find the missing value in the table, you need to use the same method. Divide the unknown length on the drawing by 12 and set it equal to the actual length in feet. Then solve for the unknown length. Here is the equation:
? / 12 = 18
To solve for ?, multiply both sides by 12:
? = 18 × 12
? = 216
Therefore, the missing value in the table is 216 inches. The complete statement is:
Length on Drawing (inches) 2 216 10
Actual length (feet) 6 18 30
