(a) To find the area of the table top, we multiply the length and width of the table:
Area = length * width = 84 * 48 = 4032 square feet.
(b) The coverage of each bottle of sealant is given as a fraction of square feet. Since we want to completely cover the table top, we divide the area of the table top by the coverage of each bottle of sealant:
Number of bottles = Area / Coverage = 4032 / 0.5 = 8064.
Since Amanda cannot buy partial bottles of sealant, she will need to buy 8064 whole bottles.
(c) Each bottle of sealant costs , so Amanda will need to spend:
Total cost = Number of bottles * Cost per bottle = 8064 * = .
Therefore, she will need to spend on sealant.
A rectangular table is 84 long and 48 wide. Amanda would like to use sealant to cover the table top. The coverage of each bottle of sealant is measured in square feet.
(a) Find the area of the table top in square feet.
Use the table of conversion facts, as needed.
(b) Amanda wants to cover the table top with sealant. She doesn't have any to begin with and she can't buy partial bottles of sealant. Each bottle of sealant covers . How many whole bottles of sealant will she need to buy in order to completely cover the table top?
(c) If each bottle of sealant costs , how much will Amanda need to spend on sealant?
