## mjneedshelp 3 years ago What is the volume of a triangular prism with a height of 7 meters and a base that is an equilateral triangle with sides of 2 meters?

1. mjneedshelp

2. FoolForMath

Sure, do you know that volume is area of the base times height?

3. order

Do you know how to get the area of a triangle?

4. FoolForMath

If algebra is right, $$7 \sqrt{3} \; m^3$$should be the answer.

5. order

Yes, I got 12.12, which is the same. Because you use hypothagorous theroem....

6. mjneedshelp

yea i do

7. mjneedshelp

thanks

8. FoolForMath

@order: what is " hypothagorous theroem"?

I did not get it.... any one can explain?

10. order

haha, sorry. Pythagorous theorem... My teacher used to call it Hypothagorous theorem... Can't get it out now!

11. FoolForMath

lol, you should sue that teacher :P

12. order

Yes! It's stuck. And I can't even spell pythagoras correctly :S

13. anisah

lol

perpendicular is sqrt 3... if you ll multiply it with 7 then it'll give area of plane?

15. order

Area of the base * Height * 1/3

16. order

sorry

17. anisah

so that = 21?

I got it.............. HATS OFF to @order God bless you

20. order

It's just what FFM said.

And what I thought before I got confused. @waqassaddique I think you got confused with a pyramid and a triangular prism.

23. order

Yes. Sorry. I was confused for a second between a pyramid and prism.. Won't happen again! :)

yes...... No problem @order, humans commit mistakes so we did

26. order

It's that answer because the area of the base is the square root of 3 and 7 is the height.

@order : legend of mathematics...well done... thanks for your time for making my dull mind to understand

28. order

No problem! You might just have a tired head :p not a dull one.
