# Thread: Converting Inches to Numbers With Powers

1. ## Converting Inches to Numbers With Powers

Can someone help me with the formula you would use to solve a problem like below

If you have a cube with a length of 15 inches, how would you display the volume in cubic inches using a number that must be to the 3rd power.
This is the question in my 6th graders assignment but I do not know what the formula would be to determine the answer.

V = l w h, so 15 x 15 x 15 = 15^3.

I would say specifically that the volume is $15^3$ cubic inches= 3375 cubic inches.
