Question

the external dimensions of a closed wooden box are 42 CM 32 CM 27 cm find the internal volume of the box if the thickness of wood is 1 cm

Answer 1

thickness=1cm
therefore length of inner box=42-2
=40cm
breath of inner box =32-2
=30cm
height of inner box=27-2
=25cm
therefore dimensions of inner box are
l=40cm,b=30cm,H=25cm

volume of inner box =l×b×h
=40×30×25
= 30,000cm cube
therefore the volume of inner box is
30,000 cm cube.

Answer 2

Answer:

The internal volume of the box is 30,000 cm³.

Step-by-step explanation:

The external dimensions of a closed wooden box are 42 cm, 32 cm and 27 cm.

The thickness of wood is 1 cm.

The internal dimensions of box are

$42-2=40$

$32-2=30$

$27-2=25$

The internal volume of the box is

$V=l\times b\times h$

$V=40\times 30\times 25=30,000$

Therefore the internal volume of the box is 30,000 cm³.
