Answer 1

Answer:

Step-by-step explanation:

Dimensions of Box(outer) : 

Length = 66 cm 

Breadth = 36 cm 

Height = 21 cm 

thickness = 0.5 cm 

Volume of box = volume of outer stuff - volume of inner stuff 

= LBH - lbh 

= 66 x 36 x 21 - [ ( 66 - 0.5) ( 36 - 0.5) ( 21 - 0.5) ] 

= (66)(36)(21) - (65.5)(35.5)(20.5)

= 49896 - 47667.625 

= 2228.375 cm³ ≈ 2228.4 cm³( volume)  = 2.2284 litres (capacity)
