Question

Find the surface area of a cube with a side length of 1/9​

Answer 1

To find the surface area, we must define what is the surface area

• Definition of Surface Area: is all the areas of the sides of the 3D shapes added up

In this case, we have a cube

⇒ which means all the sides have equal areas since all the side lengths

are equal

That means the surface area

⇒ is equal to ⇒ 6 * (Area of One Side)

'6' comes from the # of sides on a cube

Surface Area =
`6 *(1)/(9) *(1)/(9) = (6)/(9 *9) =(2*3)/(3*3*3*3) =` 2/27

Hoped that helped!
