If m∡J=30, then 2(m∡J) = 2(30) = 60
Answer:
Step-by-step explanation:
Let the rectangle have (x,y,z) as vertex in positive octant. The rectangular box has to be necessarily symmetrical about all the three axes.
Then the sides of the box would be

Volume = 
Maximize volume subject to

i.e. 
Use Lagrangian multipliers , we have
at the maximum


Dividing we get

Similarly 
Thus we get 
Hence dimensions are
(2x,2y,2z)
So dimensions are

Hello!
The correct answer is the Credit Monitoring Service.

Gonna fix some typos with your question:
Carl wants to plant a garden that is 1 1/2 yards long with an area of 3 1/2 square yards. What is the width of the garden?
So with these type of questions, we divide 3 1/2 by 1 1/2, to find the missing length:
3 1/2 ÷ 1 1/2 = 2 1/3.
The width of Carl's garden is 2 1/3 square yards.
I think 1/4 might be your answer
