Jared is putting a new deck off the kitchen. The deck will be 94.45 inches deep. He will use 16 boards that are each 5.7 inches

wide. He has to leave a small space between the boards. If the 15 spaces between the boards are all equal, how wide will they be?

16 boards that are 5.7 inches wide each make a total of 91.20 inches.
 
    16
<u>x 5.7
</u>  112
<u>+800
</u> 91.2 inches

Since the deck itself is 94.45 inches deep, we can subtract 91.2 from the number:

  94.45
<u>-91.20</u> 
   3.25 inches.

Finally, we divide 3.25 by 15, since that's the amount of spaces we want and they have to be equal:

3.25/15= .21667

We'll round that to two numbers, so we'll end up with .22.

Your final answer is .22 inches wide for each space.

Answer:

1. d=m/v

=57.6/112.9

=0.51018601

=0.510g/cm³(3s.f.)

2. m=d×v

=1.8×54

=97.2g

3. v=m/d

=63.8/12.7

=5.02362205

=5.02cm³(3s.f.)

4. v=length×breath×height

=12×2×6

=144m³

216g=0.216kg

d=m/v

=0.216/144

=0.0015kg/m³

Step-by-step explanation:

density=mass/volume

mass=density×volume

volume=mass/density

*make sure the units are correctly placed.

*g/cm³, kg/m³
