Question

The volume of a cube can be found using the equation V = s³, where V is the volume and s is the measure of one side of the cube. Which equation can be used to solved to find the side length of a cube with a volume of 999 in³?

Answer 1

s=999−−−√3 in.

s=9993 in.

s=999 in.

s=999−−−√2 in.

Answer 2

The 3 lines are on top of the 999's

Answer 3

Answer 4

Draw it, not sure what you're referring to

Answer 5

What do you think the answer is?

Answer 6

A or D

Answer 7

Hmm, why those?

Answer 8

I'm just guessing cause I have no idea how to solve it

Answer 9

Lets say we have a cube. Remember that all sides are the same length. One side is 5 ft long. If I want to solve for the volume, I need to solve for the area (s times s) multiplied by the height, (also 5).

So we have: \[5 \times 5 \times 5 = 5^3\]

\[5^3 = 125ft\]

Answer 10

125ft is the volume. If I were to want to get the sides again, I would take the 3rd root of 125. Also written as:

\[\sqrt[3]{125} = 5\]

Answer 11

S = 5

Answer 12

\[S = \sqrt[3]{125}\]

Answer 13

Does that example make sense to you?

Answer 14

Kind of but does that mean i have to do 125 x 125 x 125?

Answer 15

Since S = \[3\sqrt{}\]125

Answer 16

Woops well u know what i mean

Answer 17

Taking the 3rd root of 125 is not 125 times 125 times 125. It is you finding breaking 125 down to find three common factors.

Answer 18

Example:\[\sqrt[3]{81} = \sqrt[3]{9 \times 9} = \sqrt[3]{3 \times 3 \times 3 \times 3} = 3\sqrt[3]{3}\]

Answer 19

\[\sqrt[3]{8} = \sqrt[3]{2 \times 2 \times 2} = 2\]

Answer 20

Is this making sense?

Answer 21

Nope not even a bit.

Answer 22

What part are you not getting?

Answer 23

I have no idea what this thing is : \[\sqrt{}\]

Answer 24

Shadow, thank you so much for your help, even though I don't get it. I will ask my mom right now, and she will help me. I'm so sorry for taking away so much time from you :(

Answer 25

All good man. Good luck
