Choice D is correct. The volume,  V, of a cube can be found using the formula V = s³ , where s is the edge length of the cube. It’s given that a cube has an edge length of 41 inches. Substituting  41 inches for s in this equation yields V = 41³ cubic inches, or V = 68,921 cubic inches. Therefore, the volume of the cube is 68,921 cubic inches.
Choice A is incorrect. This is the perimeter, in inches, of the cube. Choice B is incorrect. This is the area, in square inches, of a face of the cube. Choice C is incorrect. This is the surface area, in square inches, of the cube.
