Choice A is correct. The volume of a cube can be found by using the formula $V = s^{3}$ , where $V$ is the volume and $s$ is the edge length of the cube. Therefore, the volume of the given cube is $upper V equals 68 cubed$ , or $314,432$ cubic inches. The volume of a sphere can be found by using the formula $V = \frac{4}{3} π r^{3}$ , where $V$ is the volume and $r$ is the radius of the sphere. Therefore, the volume of the given sphere is $upper V equals four thirds pi left parenthesis 34 right parenthesis cubed$ , or approximately $164,636$ cubic inches. The volume of the space in the cube not taken up by the sphere is the difference between the volume of the cube and volume of the sphere. Subtracting the approximate volume of the sphere from the volume of the cube gives $314,432 - 164,636 = 149,796$ cubic inches.
