Question

find the surface area of a cube whose edge is 10cm​

Answer 1

Answer:

There are 2 types of surface areas (total surface area and lateral surface area). As you didn't mention which surface area, here's both.

Total Surface Area

= 6a²

= 6(10²)

= 6(100)

= 600cm²

Lateral Surface Area

= 4a²

= 4(10²)

= 4(100)

= 400cm²

Answer 2

Answer:

600

Step-by-step explanation:

As,

$A=6a^2\\\\So,\\\\6 x 10^2=600$
