30 x 7 = 210
<span>5 x 7 = 35
However, if 5 x 7 = 35, 35 will be the product.</span>
A triangle has 3 sides, the total interior angels sum to 180 degrees.
A square has 4 sides, the total interior angels sum to 360 degrees.
A pentagon has 5 sides, the total interior angels sum to 540 degrees.
Do you see a trend?
Answer:
The (s) sum of interior angles equals the (n) number of sides, minus 2, times 180.
This is written as
s = (n - 2) * 180
If we put in 900 for s, we get
900 = (n - 2) * 180
5 = n - 2
n = 7
A polygon with 7 sides is called a Heptagon.
The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:

</span>So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)
Thank you for the question! I hope this helped! Have an amazing day!! :D
