a scale drawing is 10 cm:1mm Which will be larger the actual object or the scale drawing and why

10 cm:1mm

= 100 mm : 1 mm
= 100 : 1

In order to determine whether the actual object or the scale drawing is larger, we need to understand the meaning of the given scale: 10 cm:1 mm.

A scale is a ratio that compares the measurements of the scale drawing to the measurements of the actual object. In this case, the scale indicates that for every 10 centimeters (cm) on the actual object, the scale drawing represents only 1 millimeter (mm).

Now, comparing centimeters to millimeters, we know that 1 centimeter is equal to 10 millimeters. Therefore, the scale can also be expressed as 10 cm:10 mm or 1 cm:1 mm.

Based on the scale, we can determine that the scale drawing will be larger than the actual object. This is because the scale drawing represents 1 mm for every 1 cm, which means it magnifies the size of the object. In other words, the scale drawing is an enlarged representation of the actual object, making it appear larger.

So, in summary, the scale drawing is larger than the actual object because the scale magnifies the size of the object, representing 1 mm for every 1 cm, instead of the actual measurements.
