Answer 1

Answer:

12

Step-by-step explanation:

12cm are total surface area

Answer 2

Answer:

504 cm^2

Step-by-step explanation:

Solution-

There are three cubes side-by-side

And the surface area of 1 cube is 6a^2.

Therefore the total surface area would be 5a^2+4a^2+5a^2(Refer the diagram)

Therefore, a= 6cm

So, 5(6)^2+4(6)^2+5(6)^2

...... 5(36)+4(36)+5(36)

=180+144+180

=504 cm^2(Ans)
