Question

anonymous · Answer

Is the box a cube?

anonymous · Answer

Yes.

anonymous · Answer

Okay, that makes it possible to calculate.

$$l^3 = 60$$

Solve for l, and you have your answer.

anonymous · Answer

ya..

anonymous · Answer

Is it 30?

anonymous · Answer

???? I'm completely feel stuck on this.

anonymous · Answer

That's okay. We can work through it together.

$$l^3 = 60$$

What should you do to both sides to isolate the l?

anonymous · Answer

$$l = \sqrt[3]{60}$$

anonymous · Answer

Divide.

anonymous · Answer

It is the cubic root, so we do not divide in this case. The opposite of square is root, so we take the third root of 60.

anonymous · Answer

Which would be 15 right?

anonymous · Answer

The answer should come out as around 3.9.

anonymous · Answer

You can always check your answer by putting your solution to the power of 3.

anonymous · Answer

Oh.

anonymous · Answer

I see... I had to round it off.

anonymous · Answer

All you need to do is put this in your calculator:

$$\sqrt[3]{60}$$

anonymous · Answer

I didn't get that on my calculator ..

anonymous · Answer

What did you get?

anonymous · Answer

3.27

anonymous · Answer

I'm not sure how you got that, but you know how to work out the answer, and that's the important thing :)
