Question

A closed box is made up of wood which is 1cm thick.Outer dimensions of the box is 5cm×4cm×7cm.Find the volume of the wood used

Answer 1

SEE...

THE BOX IS 1CM THICK.....

SO WE HAVE TO SUBSTRACT IT FROM EACH DIAMENTION....

BUT TWICE BECAUSE DIAMENTIONS ARE FROM BOTH SIDES.....

SO....

5-1-1........=3

4-1-1........=2

7-1-1.........=5

FOR THE VOLUME OF CUBOID.....L*B*H

= 5*2*3

=30CUCM

SO THE VOLUME OF THE BOX IS 30CUCM.....

HOPE IT WILL HELP U.....
