u = 94

Step-by-step explanation:

First multiply both sides of the equation by 2.

$\frac{u-82}{2}$ ·2 = 6·2

u - 82 = 12

Then add 82 to both sides of the equation

u - 82 + 82 = 12 + 82

This gives you your answer.

A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
