Question

i am not sure how to do this one! how do i get the correct answer.

Answer 1

The volume of a cube is one hundred forty-four cubic meters. What is the volume of the square based pyramid with the same side length and height?

A) sixteen cubic meters

B) forty-eight cubic meters

C) four hundred thirty-two cubic meters

D) one thousand two hundred ninety-six cubic meters

Answer 2

@iGreen

Answer 3

You have to cube 144.

Volume of a Cube = \(s^3\), where s is the side.

Since we want to find the side length(which will also be the height), we have to cube both sides.

\(s^3 = 144\)

\(s =~ ^3 \! \! \! \! \! \sqrt{144}\)

Answer 4

So what's the cube root of 144?

Answer 5

Just type it in Google.

Answer 6

@_lilb_to_smooth_4_U_ You there?

Answer 7

one sec...

Answer 8

google says 5.24148278842 is that correct it sure is long

Answer 9

Yep.

Answer 10

ok so how i get the answer?

Answer 11

Okay, here's the formula for the Volume of a Square Pyramid:

\(V = \dfrac{1}{3} b^2 h\)

Since the height and the base are both 5.24148278842, we plug them in:

\(V = \dfrac{1}{3} (5.24148278842)^2 (5.24148278842)\)

\(V = \dfrac{1}{3} (27.4731418) (5.24148278842)\)

Can you multiply those three together? 1/3 * 27.4731418 * 5.24148278842

Answer 13

ONE SECOND ;)

Answer 14

4.79999999628 is what i got log number dude!

Answer 15

No, check again.

Answer 16

\((1/3) \times (27.4731418) \times (5.24148278842)=~?
\)

Answer 17

187.2

Answer 18

No..I'm getting something else.

Answer 19

Just copy and paste this into google:

(1/3)(27.4731418)(5.24148278842)

Answer 20

I get 48.. @_lilb_to_smooth_4_U_

Answer 21

\((1/3)(27.4731418)(5.24148278842) \rightarrow (9.15771393)(5.24148278842) \rightarrow 48\)
