Question

A cube has a surface area of 294sq. In. What is the length of the sides
49
7
6.6

Answer 1

The length of the sides is 7 In.

Explanation:

Given:

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

Now, to find the sides.

Let the side be
`a`

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

`Area = 6(side)^2`

`294=6a^2`

Dividing both sides by 6 we get:

`49=a^2`

Using square root on both sides we get:

`7=a`

Side = 7 In.

Therefore, the length of the sides is 7 In.
