Question

Im confused
A right rectangular prism and a rectangular pyramid have the same base and height. How does the volume of the prism compare with the volume of the pyramid?
A) The prism is times larger
B) the prism is 3 times larger
C) the prism is 1/3 times larger
D)the prism is 1/4 times larger HELP ME PLSSS

Answer 1

do you know the formulas for both?

Answer 2

No... I've been slacking off in geometry class for 2 days

Answer 3

ok for right rectangular prism it is \(\Large{b*h}\)
for rectangular pyramid it is \(\Large \dfrac{b*h}{3}\)

Answer 4

you can automatically tell that the prism is 3 times larger because for the pyramid you divide by 3
if you want to check, put b = 100 h =10
the volume for the prism would be 1000
the volume for the pyramid would be 333.33

Answer 5

does that help?

Answer 6

I think so...

Answer 7

just look at the formulas.
they have almost the same formulas
so if for the pyramid you divide by 3, then the prism is 3 times greater

Answer 8

So basically wht you are saying if i divide it by 3 it gave me 1/3

Answer 9

gives*

Answer 10

yes the pyramid is 1/3 times the prism
so the prism is 3 times the pyramid

Answer 11

ok I think i got it now!
