If a scale is 1 cm = 4 m, how do you find the height of an object in a scale drawing?

Back

To find the height in a scale drawing, divide the actual height by the scale factor. For example, for a 2 m tall door, 2 m ÷ 4 m/cm = 0.5 cm.

How do you convert inches to feet when using a scale?

Back

To convert inches to feet, multiply the number of inches by the scale factor in feet. For example, if the scale is 1 inch = 265 feet, then 2 inches = 2 x 265 = 530 feet.

What is the formula to calculate the actual distance from a map scale?

Back

The actual distance can be calculated by multiplying the distance on the map by the scale factor. For example, if the scale is 1 cm = 400 km and the distance on the map is 22 cm, then actual distance = 22 cm x 400 km/cm = 8800 km.

How do you determine the length of a drawing if you know the actual length and the scale?

Back

To determine the length of a drawing, divide the actual length by the scale factor. For example, if the scale is 5 cm for each meter and the actual length is 15 m, then drawing length = 15 m ÷ 1 m/5 cm = 75 cm.

If a model is built to a scale of 1:100, what does this mean?

Back

A scale of 1:100 means that 1 unit on the model represents 100 units in real life.
