Question

Diagram attached! :D Medals!

Answer 1

area of a pyramid is equal to base area + 1/2 *perimeter* slant length

Answer 2

Umm... is there a formula?

Answer 3

base area+lateral area where lateral area=1/2*perimeter*slant length for a pyramid that all side faces are the same(like yours)

Answer 4

Could you perhaps show me step by step, this problem confuses me.

Answer 5

you have slant length that is 16m(the red line)

Answer 6

Yes....

Answer 7

or wait..i think the side faces are not all the same

Answer 8

O.o? I hate this problem, too difficult.

Answer 9

ah lets start from the base area

Answer 10

...okay...

Answer 11

you got and hexagon there...6 triangles

Answer 12

...

Answer 13

you dont see that?look at the base of the pyramid only ...isnt it an hexagon?

Answer 14

=6 triangles..right?

Answer 15

idk...

Answer 16

just draw the base of your pyramid and connect all the angles

Answer 17

oh! yeah, 6 so...?

Answer 18

yeah you got 6 triangles with each triangle area given by 1/2*base*height

Answer 19

yes...

Answer 20

you got the base=10m and the height 5/[\sqrt{3}\]

Answer 21

height=5\[\sqrt{3}\] right?

Answer 22

do this 6 times and you ll find the base area=6*1/2*base*height

Answer 23

its 259.8 ... you got this man?

Answer 24

yeah, and i'm not a guy.. :P

Answer 25

ok:)

Answer 26

then from the formula --->pyramid area=base area +1/2*perimeter*slant length ypou got the base area and the slant legth right?

Answer 27

yes...

Answer 28

the perimeter is the sum of all of all the sides of the base area

Answer 29

....right...

Answer 30

what is the side of the base area?

Answer 31

10m?

Answer 32

correct

Answer 33

the sum of all sides?

Answer 34

:D yay

Answer 35

60m?

Answer 36

yes

Answer 37

:D

Answer 38

So...
PA=259.8+1/2*60*16?

Answer 39

yes...essentially you calculate 12 triangles....6 for the base area and 6 for the lateral area

Answer 40

739.8! :D is that the answer?

Answer 41

that all of them are the same

Answer 42

yes ...aprroximately 740

Answer 43

Woohoo! thanks!

Answer 44

i mean..the 6 triangles of the base area are the same and the 6 of the lateral area are the same...i hope you got that :)
