Answer :
The volume of a cube with a side length of 7 inches is calculated as 7³ which equals 343 in³, making option b the correct answer. The correct option is b. 343 in³.
To find the volume of a cube, you use the formula V = s³, where V stands for volume and s is the length of one side of the cube.
For a cube with a side length of 7 inches, the calculation would be V = 7³ or V = 7 x 7 x 7, which equals 343 in³.
This example shows how cube volume is directly related to the side length, and since all sides are equal in a cube, you simply raise the side length to the power of three to find the volume. Therefore The correct option is b. 343 in³.
