To find the answer, set up an equation:
\frac{45 \: miles}{1 \: hour}  \times  \frac{1000 \: meters}{1 \: mile}  \times  \frac{1 \: hour}{3600 \: seconds}  =
Using this set up we can cross out the units that are on opposite sides of the proportion such as miles and hours, leaving us with the desired units of meters and seconds. Then calculate m/s by multiplying 45 by 1000 meters and then dividing that value by 3600 seconds.

The resulting answer is 45mph = 12.5 m/s

Answer:

480 in3

Step-by-step explanation:

So the first thing I looked at was how to find the volume of a 3-dimensional square. Why do we have to do this? Well, we can see that the shape is made up of 3 different types of 3-dimensional cubes so to find the answer all we have to do is figure out the volume for each separate cube and add them all together.

So, to find the volume of a cube we have to multiply the area (length x width) by the height of each cube.

Let's start with the largest cube so we would multiply 5 x 12 x 4 which equals <u>v = 240</u>

Now let us do the second to largest by multiplying 8 x 5 x 4 = which equals    <u>v = 160</u>

Finally, on to the smallest cube, 4 x 4 x 5 =

<u>v = 80</u>

So now if we add <u><em>240 + 160 + 80</em></u> that will give us 480

So the answer is <u><em>480 in3</em></u>

Hope this is correct I was a little confused while I was figuring it out :0 Sorry if it is wrong :(
