So first we need to find the total number of boxes that the cookies could fit in:
Now we know that 47 boxes were made from this amount of cookies.
If Mr. Riley sells each box for 8, then we need to multiply the number of boxes by 8:
So Mr. Riley will collect a total of 376 from selling all of his cookies.
Answer:
1)Diagram attached
2)8424
3)1404
4)1569
Step-by-step explanation:
1)
Diagram is attached
2)
How many square feet of the gravel will surround the lawn:
Converting yards into feet:
1 yard =3 feet
So 80 yard =80(3) feet
=240 feet
and 150 yard =150 (3) feet
=450 feet
Area of rectangle is given by :length X width
Area of the outer border = (6+ 240+ 6 ) (6+ 450+6)
= 252 X 462
= 116424
Area of the lawn = 240 X 450
= 108000
Area of gravel border = 116424 - 108000
= 8424
Area of gravel border is 8424 ft^2
3)
Total volume when depth is 2 inches:
converting inches to feet:
1 inch= 0.083 feet
2 inches =0.1667 feet
volume = base area X depth
=8424 X 0.1667
= 1404
total volume of gravel needed for the border is 1404 ft^3
4)
Given:
A large bag of colored rock contains 5/8 of a cubic yard and costs $30
total cost of the rocks needed for the border=?
1 cubic yard = $30
converting cubic yard to cubic feet
1 cubic yard=27 cubic feet
cost of 1 cubic yard= cost of 27 cubic feet = $ 30
cost of 1 cubic feet=30/27
cost of 1404 cubic feet= 1404 X 30 / 27
= 1560
the total cost of the rocks needed for the border is $1560!
