An object's dimensions are: length of 25cm, wight of 10cm, and height of 15cm. calculate the object's density if its mass is 3000g
Use PEMDAS. Division comes before addition. start with 9/25 ÷ 18/15. You will divide those like you would normally divide a fraction, so yes, do the inverse of 18/15 and multiply that by 9/25. after you've done that, take that answer and add the 5/8 to it.

Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:

Putting the values, we get,

Thus, there are 10 sides. The regular polygon is a regular decagon.
<u>Answer:</u>
<h2>
A = 64.5 in²</h2>
<u>Steps:</u>
A = 13 × 6.5 - ((4 × 3×2)-2²)
A = 84.5 - (24 - 4)
A = 84.5 - 20
A = 64.5 in²
