Answer 2

Hey!

Given,
Dimensions of rectangular solid = 50cm , 64 cm and 72 cm.
edge of cube = 4 cm

We know,
Volume of rect. solid = l*b*h
                                 = 50*64*72 cm³
Volume of one cube = a³ = 4³ = 64 cm³

Now,
Number of cubes formed = volume of solid metal / volume of cube
                                        = 50 * 64 * 72 / 64
                                        = 3600 cubes
