Question

A cube has a surface area of 294 square cm.


Find the length of one side

Answer 1

the surface area of a cube =6*(length of each side)^2

Answer 2

Hey, @jera25617

To solve this question you need to understand the cube!
It looks like this:



Alright, so that was the basics.

Now, you are given that the Total surface area = \(6s^2 = 294\)
Thus, after solving that for 's', we get \(s^2=49 ~~~~~=> ~~~~s = 7\)

Thus, your edge length og the cube = 7cm! :D

Understood? :)
