Question

A wooden block has the following measured dimensions: height 1.25 cm; width 2.5 cm and length of 15.956 cm. Calculate its volume in ml with the proper number of significant figures.

Answer 1

`V=50mL`

Step-by-step explanation:

Hello,

In this case, by knowing that the volume of an object is computed by considering its dimensions, width, length and height, for the given measurements, we obtain:

`V=W*H*L=1.25cm*2.5cm*15.956cm\\\\V=49.86cm^3`

Moreover, since one cubic centimetre equals one millilitre, the required volume is:

`V=49.86cm^3*(1mL)/(1cm^3)\\ \\V=49.86mL`

Finally, since 2.5 cm has the fewest significant figures (2), the proper result is:

`V=50mL`

Regards.
