Day 66: Scale Drawings

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object or space that is proportionally reduced or enlarged to fit a specific size, maintaining the same ratios as the original.

Front

How do you calculate the actual size from a scale drawing?

Back

To find the actual size, multiply the measurement on the drawing by the scale factor.

Front

What does the scale 2.5 cm:0.75 mm mean?

Back

It means that 2.5 cm on the drawing represents 0.75 mm in reality.

Front

If a model is built at a scale of 1 in = 7 ft, how do you convert feet to inches?

Back

To convert feet to inches, multiply the number of feet by 12.

Front

What is the formula to find the area of a rectangle?

Back

Area = length × width.

Front

If a model window is 1.5 in wide at a scale of 5 in:25 ft, how do you find the actual width?

Back

Multiply the model width by the scale factor: 1.5 in × (25 ft / 5 in) = 7.5 ft.

Front

What is the purpose of using scale drawings?

Back

Scale drawings help visualize and represent large objects or spaces in a manageable size.

Front

How do you find the distance between two points in a scale drawing?

Back

Measure the distance on the drawing and multiply by the scale factor to find the actual distance.

Front

What is the scale factor in the scale 2 cm = 10 m?

Back

The scale factor is 10 m / 2 cm = 5 m/cm.

Front

If a parking lot's area is represented in a scale drawing, how do you find the actual area?

Back

Use the scale to convert the dimensions from the drawing to actual measurements, then apply the area formula.
