Answer:
588 sq. in.
Step-by-step explanation:
The total volume of air inside the skylight is in the shape of a pyramid, not the rectangular prism at the bottom.
So, if we look at the pyramid, it has a square base with dimensions 14 x 14. Its height is 11 - 2 = 9.
Formula for volume of a pyramid is:
V = 1/3 * Area of Base * height
Area of Base (since it is a square) = 14 * 14 = 196
Height is 9
<em>plugging into the formula, we get:</em>

</em>

<em>Hence, volume is 588 sq. in.</em>

Answer:
126°
Step-by-step explanation:
hello :
234°=360°-126°..... so:
- 234°=-360°+126°
The discount was
15%×$275 = $41.25
so the price at which the system was sold was
$275.00 - 41.25 = $233.75
The sales person receives 2% of this, or
2%×$233.75 ≈ $4.68
