Answer: 28 cube boxes.
Step-by-step explanation:
The volume of a cube can be found with this formula:
Where "s" is the lenght of any edge of the cube.
You need to find the volume of a cube box:
To find the volume of the shipping box, first we must convert the mixed number to an improper fraction. To do it, multiply the whole number part by the denominator of the fraction and add this product to the numerator.
The denominator does not change.
Then:
Knowing the dimensions of the shipping box, you can calculate its volume by multiplying its dimensions. Then, this is:
Finally, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube:
13+5=18 18-7=11
That’s the answerrrrrrrrrr
It will cost $360 to enclose a square garden.
We need to find the perimeter of the square to know the number of meter needed and multiply it to the unit cost of the fence to get the total cost.
Given:
fence = 7.50 per meter
Area of a square = 144 m²
Area of a square = s²
s = √144m²
s = 12m
Perimeter of a square = 12m x 4 sides = 48 meters.
48 meters x $7.50 = $360
