Fifty metal spheres with the radii of 4m are melted and this melted solution is poured into a cube with base dimensions of 2m x 6m. Find the height of the cube filled with solution.
Volume of a sphere = 4/3 pi r^3
there are 50 of them soo 50 * 4/3 pi (4^3) = 13404.12866 m^2
volume of cube = l * w * h (the box in the question is not a cube....l w and h are not the same value)
2 * 6 * x = 13404.12866
h = 1117 m ( are you sure you have the dimension of the spheres correct?)
