First find the area of the base. The formula is 1/2(perimeter)(apothem)
Mertsj
  • Mertsj
Find that and tell me what you get.

Yes. That's what I got.

Not we have to find the area of one of those triangles and multiply by 5. I'll draw a picture. We know the base is 10.17 and the slant height is the height of the triangle.

Find the area of that triangle and multiply it by 5

127.125

  • Mertsj
Is that one triangle or all 5?
anonymous
  • anonymous
one
anonymous
  • anonymous
5 would be 635.625
Mertsj
  • Mertsj
Now add the area of the base that we calculated earlier. That should be the total surface area.

SA = 762.75 ?

What is the area of the base?

If you look back through the posts you will find the area of the base and the area of the 5 triangles. Add them together to get the total area.

813.6
Mertsj
  • Mertsj
yes. That is the surface area.
Mertsj
  • Mertsj
Now the volume. Fortunately we are partly done with the volume because we already know the area of the base.
Mertsj
  • Mertsj
So find that number. The area of the base. To find the volume multiply these 3 numbers: 1/3, the area of the base, and the height of the pyramid which is shown in the picture to be what?

i got 13361.486
Mertsj
  • Mertsj
What is the height?
anonymous
  • anonymous
25
Mertsj
  • Mertsj
That's the slant height. Look at the picture.

24

  • anonymous
its 24
Mertsj
  • Mertsj
The slant height is the height of the triangles that make the pyramid.
Mertsj
  • Mertsj
Yes. 1/3(24)=8 so multiply 8 times the area of the base. What do you get?
anonymous
  • anonymous
1423.8

  • Mertsj
That's what I got as well. That would be m^3
