## baraha 2 years ago PLEASEEE help with geo problem :( find the volume of the regular pyramid. https://media.glynlyon.com/g_geo_2012/8/groupi77.gif

1. baraha

i got 16 sqrt 2 but its saying its wrong

2. Dido525

Well the volume is just the area of the base times height.

3. baraha

well i dont understand how it would be in square root form?

4. nubeer

did you find the area of base?

5. baraha

isnt it 16

6. nubeer

hmm no.. the base is like a triangle.. not square.

7. baraha

well how would you find it ? multiplying length and width?

8. nubeer

hmm no.. area of triangle = 1/2 *base *height,

9. baraha

so 8?

10. nubeer

yes i think so.. vol of pyramid = 1/3 * area of base * height of pyramid.

11. baraha

so 8 times 4 ? which is 32?

12. nubeer

i am not sure if 4 is the height as the diagram is very much titlted.

13. baraha

well what would you think it is? because i can always try it and see if its right or wrong. it gives me another chance. but would it be 32 sqrt 3?

14. nubeer

15. baraha

32 from the area and 3 because of 1/3 actually im not sure im really confused

16. nubeer

hmm no dont think so it should be 32/3 then

17. baraha

okay then what ?

18. nubeer

i think this should e the volume of pyramid.

19. baraha

32 sqrt 3?

20. nubeer

noo.. how you get square root.. i never get square root.. i got 32/3

21. baraha

well the answer format has this |dw:1353832060046:dw|

22. nubeer

hmm then we made some mistake earlier.. i think probably should be height or the area of base.

23. baraha

i dont know what to do :(

24. nubeer

25. baraha

like? ive been asking this for the whole day

26. nubeer

just tag people .. ask Hatrn or any other moderator.
