Answer 1

$\bf\large\underline\pink{Answer:-}$

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
