20. A milk container in the form of a cuboid is 60 cm long and 24 cm wide. How high should it be​

Answer 1

Answer:

Hello dear here is ur ans

Step-by-step explanation:

outer dimensions : 60×45×32

Thickness of wood =2.5cm

l=60−2(2.5)=55cm

b=45−2(2.5)=45cm

h=32−2(2.5)=27cm

∴ The capacity of the box = l×b×h=(55×40×27)cm  

3

=59400cm  

3

 

Total volume of box =L×B×H

=(60×45×32)cm  

3

 

=86400cm  

3

 

∴ Volume of wood used =Total volume - Actual capacity

=86400−59400

=27000cm
