(6) (Bonus) A rectangular box has its edges changing length as time passes. At a particular instant, the sides have lengths a = 150 feet, b = 80 feet, and c = 50 feet. At that instant, a is increasing at 100 feet/sec, b is decreasing 20 feet/sec, and c is increasing at 5 feet/sec. Determine if the volume of the box is increasing, decreasing, or not changing at all, at that instant.

Increasing,

Step-by-step explanation:

We are given that

a=150 feet

b=80 feet

c=50 feet

We have to find the volume of the box  of the box increasing,decreasing or not changing at all at that instant.

We know that

Volume of box=

Using the formula

Volume of box,V=abc

Differentiate w.r.t t

Substitute the values

Hence, the volume of the box is increasing .

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
