Step-by-step solution

To determine whether the volume of a cube is equal to the length of the edges cubed, we follow these steps:

  • Step 1: Recognize that a cube is a three-dimensional shape with six equal square faces. All edges of a cube are of equal length.
  • Step 2: Recall the formula for the volume of a cube, given by V=s3 V = s^3 , where s s is the length of one of the cube's edges.
  • Step 3: The question asks if the volume is equal to the edge length cubed. We note that the formula V=s3 V = s^3 clearly indicates that the volume of a cube is indeed calculated by cubing the length of its edges.

Thus, the volume of a cube is equal\mathbf{equal} to the length of the edges cubed.

Therefore, the correct answer to this problem is:

Yes
