Answer:

Step-by-step explanation:
Apparently, you're being asked to identify the sequence of steps you would use to compute the volume of the pyramid.
It seems to be a good idea to start with the formula for the volume.
Then, recognize that you need to compute B, so make that computation. The area of the base (B) is the product of the base dimensions (14)(12).
Once you have the value of B, then you can put that, along with the value of h, into the original volume formula.
Evaluating it gives the volume in cubic units.

<em>Additional comment</em>
If you're familiar with the pyramid volume formula, you know that you must compute B before you can make use of the formula. That makes the sequence be B=14(12); B=168; V=1/3Bh; V=1/3(168)(7).
However, if you're starting from scratch, it is probably good to begin with the volume formula. That is what tells you that you need to find B in the first place. This is the sequence we show below.
Answer:
galaxies.
Step-by-step explanation:
There are about stars in the universe.
The Milky Way galaxy stars.
All we need to do to find the number of galaxies is to divide the total number of stars in the universe by the number of stars in the Milky Way:
Number of galaxies = (Number of stars in the universe) / (Number of stars in the Milky Way)
Number of galaxies =
N =
N =
The number of galaxies in the universe is approximately .
