the length of the side of the cubical block = 25 cm
volume of the one cubical block = 25*25*25 cubic cm
let the required number of blocks be n.
therefore the volume of the n cubical blocks = volume of wood
n*253=300*75*50
n=12*3*2=72
thus required number of blocks are 72.

Answer:
Step-by-step explanationion:
volume of a log of wood=L×B×H
300cm×75cm×50cm
1125000cm³
volume of one cubical block=(25)³
(25×25×25)cm³
15625cm³
Now,
the number of cubical blocks of 25 CM that can be cut from a log of wood=volume of a log of wood/ volume of a cubical block
=1125000/15625
=72
