Question

A wooden bax has a external dimensions of 40cm by 30cm by 34cm. If the wood is 1 cm thick how many cm^3 of wood are there in it

Answer 1

Answer:

Step-by-step explanation:

EXTERNAL LENGTH OF BOX =40CM

EXTERNAL BREADTH OF BOX = 30CM

EXTERNAL HEIGHT OF BOX = 34CM

SINCE,WOOD IS 1CM THICK.SO,INTERNAL DIMENSION IS 1 CM LESS FROM BOTH SIDES,

SO,INT. LENGTH=40-2=38

INT.BREADTH=30-2=28

INT. HEIGHT=34-2=32

SO, VOLUME OF WOOD =EXT.VOLUME-INT.VOLUME

=40*30*34-38*28*32

=40800CM³-34048

=6752CM³
