28. A hollow cube of size 5 cm is taken, with a thickness of 1 cm. It is made of smaller cubes of size 1 cm. If 4 faces of the outer surface of the cube are painted, totally how many faces of the smaller cubes remain unpainted?

800

500

488

900

Ans.:side of cube = 5 cm

its thichness = 1 cm

so volume of outer cube = 5*5*5

volume of inner cube = 3*3*3

volume of the hollow cube = 5*5*5 â?? 3*3*3 = 98

so total no of small cubes of the size 1 cm = 98/1*1*1 = 98

we know a cube has 6 faces so total no of face = 98*6 = 588

one surface of outer cube contains a total of 25 surface of smaller cube , so when 4 surface of outer cube is painted total no of surface of small cubes i.e supposed to be painted is 4*25 = 100

so the total no of surfaces of small cube that will be remained unpainted is 588-100 = 488

no of faces remain unpainted: 588-( 25* no faces painted)
