A rectangular table is
72in
long and
36in
wide. Teresa 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.
ft2
(b) Teresa 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
7ft2
. How many whole bottles of sealant will she need to buy in order to completely cover the table top?
bottles
(c) If each bottle of sealant costs
$12.50
, how much will Teresa need to spend on sealant?
$
(a) To find the area of the table top in square feet, we need to first convert the dimensions from inches to feet:
Length = 72 in = 6 ft
Width = 36 in = 3 ft
Then we can use the formula for the area of a rectangle:
Area = length x width
Area = 6 ft x 3 ft
Area = 18 ft^2
Therefore, the area of the table top in square feet is 18 ft^2.
(b) If each bottle of sealant covers 7 ft^2, we can divide the total area of the table top by the coverage of each bottle to find out how many bottles Teresa needs:
Number of bottles = Area ÷ Coverage
Number of bottles = 18 ft^2 ÷ 7 ft^2
Number of bottles = 2.57
Since we cannot buy partial bottles of sealant, Teresa will need to buy 3 whole bottles of sealant to completely cover the table top.
(c) If each bottle of sealant costs $12.50, we can multiply the number of bottles by the cost per bottle to find out how much Teresa will need to spend:
Total cost = Number of bottles x Cost per bottle
Total cost = 3 x $12.50
Total cost = $37.50
Therefore, Teresa will need to spend $37.50 on sealant.
What is 2.57 as a whole number?
2.57 rounded to the nearest whole number is 3.
Kevin's garden is in the shape of a rectangle. It measures
12yd
long and
9yd
wide. He wants to cover the garden with mulch for the winter. The coverage of each bag of mulch is measured in square feet.
(a) Find the area of the garden in square feet.
Use the table of conversion facts, as needed.
ft2
(b) Kevin wants to cover his garden with mulch. He doesn't have any to begin with and he can't buy partial bags of mulch. Each bag of mulch covers
90.5ft2
. How many whole bags of mulch will he need to buy in order to completely cover his garden?
bags
(c) If each bag of mulch costs
$15
, how much will Kevin need to spend on mulch?
$
(a) To find the area of the garden in square feet, we need to first convert the dimensions from yards to feet:
Length = 12 yd = 36 ft
Width = 9 yd = 27 ft
Then we can use the formula for the area of a rectangle:
Area = length x width
Area = 36 ft x 27 ft
Area = 972 ft^2
Therefore, the area of the garden in square feet is 972 ft^2.
(b) If each bag of mulch covers 90.5 ft^2, we can divide the total area of the garden by the coverage of each bag to find out how many bags Kevin needs:
Number of bags = Area ÷ Coverage
Number of bags = 972 ft^2 ÷ 90.5 ft^2
Number of bags = 10.74
Since we cannot buy partial bags of mulch, Kevin will need to buy 11 whole bags of mulch to completely cover his garden.
(c) If each bag of mulch costs $15, we can multiply the number of bags by the cost per bag to find out how much Kevin will need to spend:
Total cost = Number of bags x Cost per bag
Total cost = 11 x $15
Total cost = $165
Therefore, Kevin will need to spend $165 on mulch.
10.74 as a whole number
10.74 rounded to a whole number is 11.
A rally poster is a square
36in
long and
36in
wide. We want to cover the poster with glitter. The coverage of each tube of glitter is measured in square feet.
(a) Find the area of the poster in square feet.
Use the table of conversion facts, as needed.
ft2
(b) We want to cover the poster with glitter. We don't have any to begin with and we can't buy partial tubes of glitter. Each tube of glitter covers
2ft2
. How many whole tubes of glitter will we need to buy in order to completely cover the poster?
tubes
(c) If each tube of glitter costs
$1.70
, how much will we need to spend on glitter?
$
(a) To find the area of the poster in square feet, we need to first convert the dimensions from inches to feet:
Length = 36 in = 3 ft
Width = 36 in = 3 ft
Then we can use the formula for the area of a square:
Area = side x side
Area = 3 ft x 3 ft
Area = 9 ft^2
Therefore, the area of the poster in square feet is 9 ft^2.
(b) If each tube of glitter covers 2 ft^2, we can divide the total area of the poster by the coverage of each tube to find out how many tubes we need:
Number of tubes = Area ÷ Coverage
Number of tubes = 9 ft^2 ÷ 2 ft^2
Number of tubes = 4.5
Since we cannot buy partial tubes of glitter, we will need to buy 5 whole tubes of glitter to completely cover the poster.
(c) If each tube of glitter costs $1.70, we can multiply the number of tubes by the cost per tube to find out how much we will need to spend:
Total cost = Number of tubes x Cost per tube
Total cost = 5 x $1.70
Total cost = $8.50
Therefore, we will need to spend $8.50 on glitter.
