Question

Given a cube with a volume of 27 cm3, what is the volume of a square pyramid that can fit perfectly inside the cube? (4 points)

3cm3
6cm3
9cm3
12cm3

I KNOW that the answer is 9cm3, my issue is that I don't know how. I always thought that a the volume of a pyramid was 1/6(b^3) or the volume of a cube but apparently that's not right. I'm confused on how to reach the answer if someone could please show and explain to me the process of getting to 9cm^3

Answer 1

its c

Answer 2

@nciezki12 I know, how how did you reach that conclusion?

Answer 3

27 divided by 3 = 9

Answer 4

Yes why did you choose to multiply it by 1/3 though?

Answer 5

Is the volume of a pyramid = to 1/3 of the volume of a cube? If so why?

i said this is his qustion

Answer 19

you are supposed so explain to him how to get the answer.

Answer 20

and i told him 27 divided by 3 = 9

that is my exlanain

Answer 21

1/3(B)(h) is the formula for the volume of a pyramid. The volume of a square is b^3 and we know that because the volume of the cube is 27 that b = 3. B = side times side so
1/3 (3*3)(h) = 1/3(9) in which h = 3 so 1/3 27 the answer is 9

Answer 22

I get it.

Answer 23

Sorry, I had to work it out xD I get it now. Im so sorry

Answer 24

@Mrs.Peter V=lwh/3 :)

Answer 25

Will this always work ? 1/3 the volume of a cube equals the volume of a pyramid that is inscribed within the cube?

Answer 26

yes it will

Answer 27

Just multiply LxWxH /3

Answer 28

yea

Answer 29

@nciezki12 @iBacon thank you guys so much for your help! I was very confused but not anymore. :)

Answer 30

But it gave you the LxWxH. So just divide it by 3. :)

Answer 31

@nciezki12 next time help him don't just tell him the answer it's against CoC

Answer 32

ok

Answer 33

@nciezki12 @iBacon Thanks again, I thought both of you did a great job in helping me :)
