Question

The body of a microbe consists of 3 parts of different lengths. The lengths are shown using different models. Find the total length of the microbe.

• A. $\text{0}.033mm$
• B. $\text{0}.022mm$
• C. $\text{0}.023mm$
• D. $\text{0}.012mm$

Answer 1

The correct option is A $\text{0}.033mm$

Length of part 1:

There are 1 rod and 3 units.

One rod represents 0.01 and one unit represents 0.001.

Hence, this is equivalent to 0.013

Length of part 2:

There are 6 units.

This is equivalent to 0.006.

Length of part 3:

There are 1 rod and 4 units.

This is equivalent to 0.014.

Total length = 0.013 + 0.006 +0.014 = 0.033

Hence, total length of the microbe = 0.033 mm.
