can someone help me with this plzzz ???​

Answer 1

Answer:

1000cm²

Step-by-step explanation:

side of cube= 10

then , one more cube is join with of same side to form an rectangle

Therefore:

length of the cuboid 'l' =10+10=20 cm

breath of the cuboid 'b' =10 cm

height of the cuboid 'h' =10 cm

so,

area of cuboid= 2(l×b+b×h+h×l)

= 2(20×10+10×10+10×20)

= 2(200+100+200)

= 2(500)

= 1000cm²

please mark my answer as brainlist
