-The length is
feet.
- The width is
feet.
- The height is
feet.
2. The box has one base. The cost of the base is:

3. It has four sides. The cost of the sides are:

The answer is: The total cost is 
Answer:
23/24
Step-by-step explanation:
To find the sum you must ad.
Fractions can only be added and subtracted when the denominators (the bottom numbers) are the same.
24 is the smallest number that 2, 3 and 8 go into.
1/2 = 12/24, 1/3 = 8/24, 1/8 = 3/24

23/24
If you move the decimal from left to right, then you make it either a whole number or a percentage.
Answer: 10.5 miles
Step-by-step explanation: If she runs 7 miles for 50 minutes, if you half it, she runs 3.5 miles in 25 minutes. This means if you add 7 and 3.5 miles, you would add 50 and 25 minutes,
So 10.5 miles in 75 minutes in your answer
The length of the rope needed is 15 feet
Given the following parameters;
- Height of the pole = 9 foot
- The distance from the <u>rope away from the base </u>of the pole is 12 feet
Required
To get the length of the rope, you will use the pythagoras theorem expressed as:
Substituting the given parameters:
c² = 9² + 12²
c² =81 + 144
c² = 225
c = √225
c = 15 feet
Therefore the length of the rope needed is 15 feet
