7 x 7 x 7 = 343

Answer 2

When a number is squared; it just means it is multiplied by itself. Example 4 x 4 = 16. Therefore 4 squared would equal 16. The answer to your question is 7. 7 x 7 = 49
Therefore if 7 is cubed, meaning 7 x 7 x 7 = 343.

You have some good explanations above. I will add one more point to them. Think of the squaring operation as finding the area of figure which is square in shape and has 7 units as its length. now you have 49 small squares within that big square , with each of them having one unit as its side length.It makes more sense. Similarly, think of a cube with all its sides having length of seven units.Seven, when cubed gives the volume of that cube with seven units sides.it means that the big cube will have 343 small cubes of
one unit sides. You can improve this understanding by playing with a Rubec Cube.One side gives you the idea of square and the whole Cube explains the cube idea.

Answer 8

You now have the answer, but you should test your understanding. What number equals 4 when squared, and sixteen when cubed? Then try What number equals nine when squared and 27 when cubed? Work your way up to an answer of 10. Its best to understand. Then you can get any answer.
