The thickness of the wood on each sides is 1.5 cm. Find:
The internal dimensions of the box and
The volume of wood used to make the box​

Answer 1

Answer:

Step-by-step explanation:

Given ;

External dimensions of the wooden box

L=15

B=10

H=8

Volume=15*10*8

=1200cc

Width of the box=1.5

Sol:

The internal dimensions=length -twice of width

Therefore

length=15-(1.5*2)

=12

b=10-(1.5*2)

= 7

h=8-(1.5*2)

=5

Internal volume= l*b*h

=12*7*5

=420cc

Volume of the box used= 1200cc-240cc

=780cc
