If the surface area of a cube is 294, whats the length of the cube?

tatyana61 [14]

Answer:

Step-by-step explanation:

Total number of surfaces of cube are 6.

Each surface is square.

And area of square is (side)^2

That means, total surface area will be 6 * (side)^2

From question,

294 = 6 * (side)^2 ( Surface area given)

=> 294 ÷ 6 = ( side) ^2

=> 49 = side^2

=> √49 = side

=> 7 = side

So, length of edge of cube is 7

Please help! Will give brainliest! Trig ratio!

DiKsa [7]

Good question!

First of all, you need to be aware of the following trigonometrical ratios\functions:

For angle A:

adjacent=12
opposite=35
hypotenuse=37

Hence:
$cos(A)= \frac{12}{37} 
\\~\\
sin(A)= \frac{35}{37} 
\\~\\
tan(A)= \frac{35}{12}$

I hope that helps!

I am with you if you faced any difficulties!
