what's the prism ? what's pyramid? make your figure properly ... this shouldn't be difficult.

miyuri what is 12 there?

experimentX yeah but how can i find the volume and total area?

MiyuruBest ResponseYou've already chosen the best response.2
It would be essential in finding the volume...

MiyuruBest ResponseYou've already chosen the best response.2
To find the total area multiply the area of triangle by 6 + area of hexagon..

volume of pyramid = 1/3* area of hexagon * height

Total area = \[(\frac{15*10}{2}*6)+(\frac{10*9}{2}*6)\]

yeah ... looks like that's correct!!

Gee! thanks a lot!!!!! but how is this? find the volume of the region outside the pyramid and inside the prism.

experimentXBest ResponseYou've already chosen the best response.1
find the volume of pyramid ... find the volume of prism ... subtract 1 from 2

MiyuruBest ResponseYou've already chosen the best response.2
Volume = \[(\frac{10*9}{2}*6)*\frac{1}{3}*12  (\frac{10*9}{2}*6*12)\]

lol ... you did the opposite? is height 12??
 one year ago

MiyuruBest ResponseYou've already chosen the best response.2
I took the height of the pyramid...
 one year ago

experimentXBest ResponseYou've already chosen the best response.1
should be something like this if 12 is height \[  (\frac{10*9}{2}*6)*\frac{1}{3}*12 + (\frac{10*9}{2}*6*12) \]

MiyuruBest ResponseYou've already chosen the best response.2
Oops yeah @experimentX I changed the sides of the equation... :D

well ...i guess that it is!!

so 4320 is the volume?=)

What is the area of the base and the height?
 one year ago

MiyuruBest ResponseYou've already chosen the best response.2
Yeah @gandako U are correct.. volume=4320

MiyuruBest ResponseYou've already chosen the best response.2
I found the height from the triangle drawn above.. x=12

gandakoBest ResponseYou've already chosen the best response.0
but how about the are of the base @Miyuru ?

MiyuruBest ResponseYou've already chosen the best response.2
Base = side of the hexagon

From which step are you confused?

gandakoBest ResponseYou've already chosen the best response.0
here: volume of pyramid=1/3 * area of the base *height how can get the are of the base?
 one year ago

MiyuruBest ResponseYou've already chosen the best response.2
Here the base is the hexagon and it's area is six times the area of a triangle...
