the ratio of the model to the actual size is 1in 85 ft estimate the height of the building if the model is 1.5 inches tall
1.5 * 85 = ?
To estimate the height of the actual building, we first need to find the scale factor between the model and the actual size. In this case, the ratio of the model to the actual size is 1 inch to 85 feet.
To find the scale factor, we divide the number of inches in the model by the number of feet in the actual size:
Scale factor = 1 inch / 85 feet
Next, we can use this scale factor to estimate the height of the building.
Given that the height of the model is 1.5 inches, we can set up a proportion to find the estimated height of the building:
1 inch (model) / 85 feet (actual) = 1.5 inches (model) / x feet (actual)
To solve for x (the height of the building in feet), we can cross-multiply:
1 inch * x feet (actual) = 85 feet * 1.5 inches
Simplifying the equation:
x = (85 feet * 1.5 inches) / 1 inch
Multiplying the numbers:
x = 127.5 feet
Therefore, the estimated height of the building is 127.5 feet.
Note: It's important to remember that this is an estimate based on the given scale. The actual height of the building may vary.
