Answer:

5610.6

Explanation:

Volume of a polygonal pyramid = area of polygon × height of prism

Finding the area of the polygon:

Area of a regular polygon = # of sides × side length × apothem × 1/2
Given:

  • # of sides = 6
  • Side length = 12
  • Apothem = 10.39

Plugging these values into the formula we get

6 × 12 × 10.39 × 1/2

==> multiply 6 by 12

72 × 10.39 × 1/2

==> multiply 72 by 10.39

748.08 × 1/2

==> divide 748.08 by 2

Area of polygon = 374.04

Finding volume of polygonal prism

Again we have volume = area of base × height of prism

Here we have area of prism = 374.04 and height = 15

So volume = 374.04 × 15 = 5610.6
