Question

Multiply 3.2 mm times 5 mm and express the answer to the correct number of significant figures.​

Answer 1

`\large \boxed{\text{ 20 mm}^(2)}`

Step-by-step explanation:

In multiplication and division problems, your answer can have no more significant figures than the number with the fewest significant figures.

`\text{3.2 mm} * \text{5 mm} = \text{16 mm}^(2)`

There are two significant figures in 3.2 and one in 5.

`\text{You must round to one significant figure and report the answer as $\large \boxed{\textbf{ 20 mm}^{\mathbf{2}}}$}`
