Heya buddy,
here is your answer
*Rectangular metallic block's*
length = l = 30cm
breadth = b = 25cm
height = h = 8cm
volume = l×b×h
= 30×25×8
= 6000cm²
*Rectangular slice's*
l = b = h = 5mm = 0.5cm
volume = l×b×h
= 0.5×0.5×0.5
= 0.125cm²
Number of slices in the rectangular block = volume of block / volume of slice
= 6000 / 0.125
= 6000 × (1000/125)
= 48000
Hence 48000 rectangular slices can be fitted on it.
Hope this helps
thank you
