volume= l×b×h

= 144m^3
CSA = area of four walls

= 2(8+6) 3
= 2×14×3
= 84m^2

Answer:
For volume
l*b*h= 8*6*3
=96
and for area of walls
wall 1 = l X h = 8 X 3
= 24
wall 2 = b X h = 6 X 3
= 18
wall 3 = wall 1
reason : wall 3 is opposite of wall 1 and opposite sides equal
wall 4 = wall 2
same reason also applies here
area of walls = 2x 24 + 2 X 18
= 48 + 36 = 84
volume = 96
area of walls=84
