Carmen plans to paint the inside of her swimming pool before she fills it. The pool is a rectangular prism with a length of 20 feet, a width of 10 feet, and a depth of 5 feet. (Note: the top of the pool is open and will not be painted.) How many square feet of surface area will she paint?
1000
700
300
500

1000

Step-by-step explanation:

length x width x height

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 : )
