The correct solution is C

Subtract 6 from both sides of the equation
3x + 6 - 6 = 21 - 6
3x = 15

Then divide both sides by 3

$\frac{3x}{3} = \frac{15}{3}$

x = 5

All triangles are similar.
.. x/3 = 27/x
.. x^2 = 81
.. x = 9

.. y = √(x^2 -3^2) = √72
.. y = 6√2

Since a cube has 6 sides with equal length and width for area, we can simply do 5 x 5 equaling 25. Then, we must multiply 25 by 6 which equals 210 square feet.
