given: l=66cm
b=36cm
h=21cm
tsa of four walls are
2(lb+bh+hl)-lb use this formula and put the value of lbh u will get the answer
what ever the answer u will get multiply it with 0.5cm then u will get the answer
after this
find the volume of a cuboid i.e., l*b*h then u will get the volume also
I hope this will help you

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)
