What is a scale drawing?

Back

A scale drawing is a representation of an object or area that is proportionally smaller or larger than the actual size, using a specific ratio to maintain accuracy.

Front

How do you calculate actual distance using a scale?

Back

To calculate actual distance, multiply the measured distance on the drawing by the scale factor. For example, if the scale is 1 cm = 5 m and the measured distance is 3 cm, the actual distance is 3 cm x 5 m/cm = 15 m.

Front

What does the scale 1/4 cm = 12.5 miles mean?

Back

It means that every 1/4 cm on the map represents 12.5 miles in real life.

Front

If a scale is 2 cm = 10 m, how many meters does 1 cm represent?

Back

1 cm represents 5 m, since 10 m divided by 2 cm equals 5 m/cm.

Front

What is the actual distance if the measured distance is 7 cm on a map with a scale of 1/4 cm = 12.5 miles?

Back

The actual distance is 350 miles.

Front

How do you convert a scale drawing measurement to real life?

Back

Multiply the measurement from the drawing by the scale factor to find the real-life measurement.

Front

What is the actual length if a blueprint shows 5 cm and the scale is 3 cm = 4.5 m?

Back

The actual length is 7.5 m.

Front

If a model is built at a scale of 5 in : 25 ft, how wide is a window that is 1.5 in wide in real life?

Back

The actual width of the window is 7.5 ft.

Front

What is the formula to find the length on a drawing if you know the actual length and the scale?

Back

Length on drawing = Actual length / Scale factor.

Front

If a blueprint uses a scale of 3.5 cm = 17.5 m, what is the scale factor?

Back

The scale factor is 5 m/cm, since 17.5 m divided by 3.5 cm equals 5 m/cm.
