The minimum surface area that such a box can have is 380 square
<h3>How to determine the minimum surface area such a box can have?</h3>
Represent the base length with x and the bwith h.
So, the volume is
V = x^2h
This gives
x^2h = 500
Make h the subject
h = 500/x^2
The surface area is
S = 2(x^2 + 2xh)
Expand
S = 2x^2 + 4xh
Substitute h = 500/x^2
S = 2x^2 + 4x * 500/x^2
Evaluate
S = 2x^2 + 2000/x
Differentiate
S' = 4x - 2000/x^2
Set the equation to 0
4x - 2000/x^2 = 0
Multiply through by x^2
4x^3 - 2000 = 0
This gives
4x^3= 2000
Divide by 4
x^3 = 500
Take the cube root
x = 7.94
Substitute x = 7.94 in S = 2x^2 + 2000/x
S = 2 * 7.94^2 + 2000/7.94
Evaluate
S = 380
Hence, the minimum surface area that such a box can have is 380 square

Answer:
She needs 4 yards.
Step-by-step explanation:
To multiply fractions, you just multiply the whole number by the numerator of the fraction.
<em>The numerator is the top number of a fraction.</em>
<em>The denominator is the bottom number of a fraction.</em>
You can think of the whole number 6 as the fraction 6/1.
<h3>Step 1</h3>
Multiply 6/1 by 2/3
6x2=12
1x3=3
So, 6/1x2/3=<u>12/3</u>
<u></u>
<h3>Step 2</h3>
Now you need to simplify the fraction
Because the numerator is a muliple (number that can be devided by) of 3, devide the numerator by the denominator.
12÷3=4
