How do you determine the width of an object in a scale drawing?

Back

To determine the width of an object in a scale drawing, you multiply the actual width by the scale factor (drawing width = actual width x scale ratio).

If a scale is given as 5 cm : 2 m, what does this mean?

Back

This means that 5 centimeters on the drawing represents 2 meters in real life.

Front

How do you convert a measurement from a scale drawing to actual size?

Back

To convert a measurement from a scale drawing to actual size, divide the measurement on the drawing by the scale ratio.

Front

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

Back

Actual length = (Length on drawing) x (Actual length per unit on drawing).

Back

5 inches represent 20 feet (20 feet ÷ 4 feet per inch = 5 inches).

Front

What is the importance of scale in drawings?

Back

The scale in drawings is important because it allows for accurate representation of real-world dimensions in a manageable size.

Front

How do you find the scale factor from a drawing to real life?

Back

The scale factor can be found by dividing the actual measurement by the measurement on the drawing.

Front

What is the relationship between centimeters and meters in scale drawings?

Back

1 meter equals 100 centimeters, so when converting between the two, you can multiply or divide by 100.

If a scale drawing shows a distance of 3 cm representing 6 m, what is the scale ratio?

Back

The scale ratio is 1 cm : 2 m (since 3 cm represents 6 m, dividing both by 3 gives the ratio).
