You can put this solution on YOUR website! The surface area of this cube is 21.66 square yards. What is the value of j?
-------
If "j" is an edge, each side has area = j^2
----
The surface area is 6j^2
------
Equation:
6j^2 = 21.66
j^2 = 3.61
j = sqrt(3.61) = 1.9 yrd

j is used in electrical engineering for the sqrt(-1), since i or I is used for current.

Surface area and sq yds is a puzzle, tho.
