(1)
Where:
- Width, measured in centimeters.
- Length, measured in centimeters.
- Height, measured in centimeters.
If we know that 
, 
and

Answer:
Step-by-step explanation:
Step-by-step solution:
7x + 3 + 6x + 11 = 0
7x + 6x + 11 + 3 = 0
13x + 11 + 3 = 0
13x + 14 = 0
13x = 0 - 14
13x = -14
x = -14 / 13
x = -1.077 approx.
