Answer:
Volume = 1114.1 
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by:

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).
Then the square base of the pyramid has an area given by: 
Finally,we can now write the volume of the pyramid as:

Rounding the answer to a tenth of a cubic inch, we get:
Volume = 1114.1

Answer:
$2.90
Step-by-step explanation:
<u>Lets look at the information given:</u>
Scott made 3 necklaces
$14.40 is the cost for both the beads and pendants for all 3 necklaces
$5.70 was the cost of just beads for all 3 necklaces
Each necklace has 1 pendant
The first step to solving this equation is subtracting the cost of the beads from the total cost for the necklaces:
$14.40 - $5.70= $8.70
Now we know that cost for the 3 pendants for all 3 necklaces was $8.70, but we need to find how much EACH pendant costs. To find out, we simply divide the total cost for all 3 pendants by 3:
$8.70 ÷ 3 = $2.90
So each pendent costs $2.90
