Find the sum of the measures of the interior angles of a regular heptagon. User: Find the volume of a square pyramid with base edges of 18 feet and a height of 14 feet.

Weegy: The formula for the volume of a square pyramid is: 1/3bh^2. So: 1/3(14)(18^2) V = 1512 feet cubed User: Find the lateral area of a triangular prism with base edges of 5cm, 12cm, and 13 cm. The height of the prism is 14cm. Weegy: The lateral area is the perimeter of the base times the height, (5 + 12 + 13)(14). I'll let you do the arithmetic.
BTW this is just the sum of the areas of 3 rectangles that form the sides of the prism: (5)(14) + (12)(14) + (13)(14). (More)

An easy way to find the sum of the measures of the interior angles of a regular heptagon is to use the formula for finding the sum of interior angles of a regular polygon.
Si= sum on interior angles
n= number of sides
Si = 180(n - 2)
Since a heptagon has 7 sides, we just plug in 7 for "n"
Si = 180(7 - 2)
Si = 180(5)
Si = 900
The lateral area of a triangular prism with base edges of 5cm, 12cm, and 13 cm and a base height of 14cm is:
(5 * 14) + (12 * 14) + (13 * 14) = 420

Given Isosceles trapezoid EFGH. The measure of angle HGF = 5y - 2 and the measure of angle EFG = 4y + 4. Find y.

Weegy: Sir/Madam The answer is 5y-2=4y+4, y=6. User: Is there a way to send a picture of a figure to help answer a certain question better? Weegy: Yes. You can upload the picture to a free filehosting website and link it here. Like this one for example: (More)

(5)(14) + (12)(14) + (13)(14).

Weegy: (5 * 14) + (12 * 14) + (13 * 14) = 420 (More)
