two cubes are joined end to end
means
breadth=4cm no change
height=4cm. no change
but
length= 4cm + 4cm 8cm
put all the values in the formulae
AREA OF CUBOID = 2(L×B+B×H+H×L)
AREA OF CUBOID = 2(8×4+4×4+4×8)
AREA OF CUBOID = 2(80)
AREA OF CUBOID = 160cm^2
means
breadth=4cm no change
height=4cm. no change
but
length= 4cm + 4cm 8cm
put all the values in the formulae
AREA OF CUBOID = 2(L×B+B×H+H×L)
AREA OF CUBOID = 2(8×4+4×4+4×8)
