Answer:

Step-by-step explanation:

Length of the third board = Total length - ( sum of other two boards)

= 21.35 - ( 8.2 + 6.42)

= 21.35 - 14.62

= 6.73 m

The batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius.

mr_godi [17]

For this unit conversion problem, you'll need to know:

1 m = 100 cm

Now let's convert with this conversion ratio!

$0.03 \frac{W}{m C} \times \frac{1 m}{100 cm} = 0.003 \frac{W}{cm C}$
