Sum of volumes of spherical bullets that can be cast from a rectangular block of metal will have same volume, as that of the block.

As we know that, volume of the rectangular block of metal=lbh. Also, volume of spherical bullets =

Given that, dimension of rectangular block of metal is 11 dm × 1 m × 5 dm = 110 cm × 100 cm × 50 cm and diameter of spherical bullets = 5cm (radius = = cm)

Therefore, number of small bullets that can be made from the block =

spheres
