Question

how many cubical blocks of side 25cm can be cut from a log of wood of side 3m by 75 cm by 50m .assuming that there is no wastage.

Answer 1

hiii!!!

here's ur answer...

given the side of the cubical block is 25cm.

volume of the cubical block = side³

= 25×25×25

= 15,625cm³

length of the log of wood is 3m = 300cm

breadth is 75cm

and height is 50m = 5000cm

volume of the wooden log = l×b×h

= 300×75×5000

= 112,500,000cm³

hence no. of cubical blocks can be cut from the wooden block = 112500000/15625

= 7200

7200 cubical blocks can be cut from the wooden log.

hope this helps..!

Answer 2

volume of log of wood=l×b×h
3m=300cm
75cm
50m =5000cm
volume =300cm×75cm×5000cm
volume=112500000
cubical box to be made=25cm
25÷112500000
4500000
