Answer 1

Answer:

this is your answer.....

Answer 2

Answer:

640 cm2

Step-by-step explanation:

two cubes are joined

so the resulting height of cube remains same i.e. 8cm

new length=(8+8) cm=16cm

and breadth remains 8cm

so the surface area =2(lengthxbreadth+breadthxheight+heightxlength)

=2(16x8+8x8+8x16)

=2(128+64+128)

=2x320

=640

hope it's correct..I mean i hope that I have calculated it correctly !
