Question

room is 8 metre long 6 metre wide and 3 metre height find the volume and area of four walls
give step by step answer​

Answer 1

Answer:

volume= l×b×h

= 8×6×3

= 144m^3

CSA = area of four walls

= 2(l+b) h

= 2(8+6) 3

= 2×14×3

= 84m^2

Answer 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
