The diagonal of the rectangular solid is 
Explanation:
The length of the rectangular solid is 
The width of the rectangular solid is 
The height of the rectangular solid is 
We need to determine the diagonal of the rectangular solid.
The diagonal of the rectangular solid can be determined using the formula,

Substituting the values
,
and
, we get,

Squaring the terms, we get,

Adding the terms, we have,

Simplifying, we have,

Thus, the diagonal of the rectangular solid is 
3(1/2x +4) = 2x +2
Use distributive property by multiply 3 by each term on the left side:
3/2x + 12 = 2x + 2
Subtract 12 from both sides:
3/2x = 2x -10
Subtract 2x from both sides:
-1/2x = -10
Multiply both sides by -2:
x = 20
Answer: x = 20
