No.
Since w = 8, you must replace the variable with the number associated to it.
So, it would be 5 + 8 = 58
5 + 8 is not equal to 58, it is equal to 13.
If you wanted to find out what w was, simply subtract 5 on both sides.
w = 58 - 5
What type of equation? I'm assuming you may mean PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction), meaning that when solving an equation first you solve anything that's in parenthesis. After that you do exponents and then either multiplication or division, going left to right if there are multiple parts of the equation that require you to do multiplication or division. Then you move on to addition and subtraction, the same rules with multiplication and division apply. Hopefully I explained this well.
The volume of the box is given by:
Where,
w: width of the box
h: height of the box
l: length of the box
Substituting values:
The volume of the box in inches is:
Then, the volume of each penny is:
Where,
r: coin radius
h: coin height
Substituting values:
Then, the number of coins that fit in the box is:
Answer:
the number of pennies that would fit in the box is:
The perimeter is: " 331. 2 cm " .
