Hello! A cuboid is a shape with 6 faces. Since all the measurements in a cuboid are equal, every face would have the same area. So you do 384/6 which is equal to 64. If every squares area is 64, then the length and width of the square would be the square root of 64, which is 8. So you have your length width and height of the cube, 8. All you have to do now is do 8*8*8 which is 512. So your answer is 512 inches cubed. :)
