Scale Drawings

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or space that maintains the proportions of the original, using a specific ratio to convert real dimensions into smaller or larger dimensions.

What does the term 'scale' mean in the context of drawings?

Back

In drawings, 'scale' refers to the ratio of the size of the drawing to the size of the actual object. For example, a scale of 1 inch = 20 feet means that 1 inch on the drawing represents 20 feet in reality.

Front

How do you convert measurements from a scale drawing to actual dimensions?

Back

To convert measurements, multiply the measurement on the drawing by the scale factor. For example, if the scale is 1 cm = 3 in and the drawing shows 2 cm, the actual size is 2 cm x 3 in/cm = 6 inches.

If a scale drawing has a scale of 1 cm = 5 m, what is the actual length of a line that measures 4 cm on the drawing?

Back

The actual length is 4 cm x 5 m/cm = 20 meters.

Front

What is the importance of using scale in drawings?

Back

Using scale in drawings allows for accurate representation of large objects or spaces in a manageable size, making it easier to visualize and plan.

Front

What is the formula to find the actual size from a scale drawing?

Back

Actual Size = Measurement on Drawing x Scale Factor.

Front

If a model is built to a scale of 1:10, how does this affect the size of the model compared to the real object?

Back

The model is 10 times smaller than the actual object. For every 1 unit of measurement on the model, it represents 10 units on the real object.

What is the scale of a drawing that shows a room measuring 12 ft by 16 ft as 3 in by 4 in?

Back

The scale is 1 in = 4 ft, since 3 in represents 12 ft and 4 in represents 16 ft.

Front

How do you find the scale factor if a drawing measures 2 inches and the actual object is 10 feet?

Back

First, convert 10 feet to inches (10 ft = 120 in). Then, the scale factor is 120 in / 2 in = 60. So, the scale is 1 in = 60 in.

What is the actual height of an object if it measures 5 cm on a scale drawing with a scale of 1 cm = 2 m?

Back

The actual height is 5 cm x 2 m/cm = 10 meters.
