Length of a carton :

Width of the carton :

Height of the carton :

Volume of the carton :
= Length × Width × Height



Therefore, the volume of the carton = 21.85 feet.
Answer:

Step-by-step explanation:
The formula for calculating the volume of a rectangular prism is length x width x height.
To work this out you would multiply all the lengths together.
1) Multiply the lengths together

This is because you are calculating the area of one face and multiplying it by the height.

Answer:
x=11.5
Step-by-step explanation:
You want to isolate x. The first thing you have to do is get rid of that tricky fraction. To do this, you have to multiply the fraction by its denominator to cancel the denominator out and leaving you only with the numerator. You would also have to multiply 3 by 5.5 too. (Multiplying by the denominator only gets rid of the denominator and leaves the numerator alone. However, in your case, the numerator is one, so by getting rid of the denominator you get 1x. This can just be written as x.)
Equation would look like this:
x+5=16.5
You subtract 5 from both sides, and 16.5 minus 5 is 11.5
Equation would now look like this:
x=11.5
Answer:
Part a) The equation is 
Part b) 
Step-by-step explanation:
Let
p -----> the number of paintings
we know that
Break even is when sales are equal to cost.
The linear equation that represent this problem is

Solve for p
Subtract p both sides


Divide by 7 both sides


Rewrite

Check the solution

substitute the value of p
