Hello Mate!
External direction = 84 cm × 75 cm × 64 cm
Inner length = 84 cm - ( 2 + 2 ) cm
= 80 cm
Inner breadth = 75 cm - ( 2 + 2 ) cm
= 71 cm
Inner depth = 64 cm - ( 2 + 2 ) cm
= 60 cm
So, inner volume = 80 cm × 71 cm × 60 cm
= 340800 cm³
Outer volume = 84 cm × 75 cm × 64 cm
= 403200 cm³
Outer - Inner volume = ( 403200 - 340800 ) cm³
= 62,400 cm³
Have great future ahead!

Answer:
62400 cm cube
Step-by-step explanation:
inner length-84-(2+2)=80cm
inner breadth-75-(2+2)=71cm
inner depth -64-(2+2)=60cm
inner volume --- (80*71*60)cm cube
=340800 cm cube
outer volume ----(84*75*64)cm cube
=403200 cm cube
outer volume - inner volume
403200-340800
=62400 cm cube.
so,ans is 62400 cm cube
