Answer:

The length of the sides is 7 In.

Step-by-step explanation:

Given:

A cube has a surface area of 294 sq. In.

Now, to find the sides.

Let the side be [tex]a[/tex]

Putting the formula of area to get the length of side:

[tex]Area = 6(side)^2[/tex]

[tex]294=6a^2[/tex]

Dividing both sides by 6 we get:

[tex]49=a^2[/tex]

Using square root on both sides we get:

[tex]7=a[/tex]

Side = 7 In.

Therefore, the length of the sides is 7 In.
