What is the surface area of a cube with side lengths of 1/7 Please help

-BARSIC- [3]

Answer: 0.122449

Step-by-step explanation:

If one side is 1/7, first convert that into a decimal, which is 0.14286. Than square that 0.14286 x 0.14286= 0.020408. That’s the area of one square. Now multiply that by 6 (the number of sides in a cube) and you get 0.122449.

jenyasd209 [6]

Answer:

$6a^{3}$

Step-by-step explanation:This is a very simple question.

We all know that the equation or formula for area is...

A= L*W

So multiply...

$2a^{2} *3a$ = $6a^{3}$

Since 3a has an exponent power of 1 and you add the exponent power when multiplying...

The result would be... $6a^{3}$ .

Hope this helps:)
