Answer:
Cost of wallpaper for the kitchen is $795.6
Step-by-step explanation:
We have that the dimensions of the kitchen are given by,
Length = 12 feet, Width = 14 feet and Height = 10 feet.
Since, we know, wallpaper is applied on the 4 walls,
Thus, Area of the four walls = 2( Length × Height + Width × Height)
i.e. Area of the walls = 2( 12×10+14×10) = 2×260
i.e. Area of the walls = 520 feet²
Since, the cost of of wallpaper per foot² is $1.53
Thus, the cost of 1680 feet² will be 1.53 × 520 = $2570.4
Hence, the cost of wallpaper for the kitchen is $795.6
Answer:
The cost to wallpaper kitchen at rate of $1.53 per foot² is $795.6
Step-by-step explanation:
Given : A kitchen is 12 ft x 14 ft x 10 ft
We have to calculate the cost to wall paper at $1.53 per foot².
Since, kitchen has three dimension of different length thus it is in the shape of a cuboid with dimension,
width: w = 12 ft
length: l = 14 ft
height: h = 10 ft
Since wallpaper will be pasted on walls of kitchen only.
So, it will be on 4 walls and thus the area of 4 walls will be given by,
[tex]Area=2(length \times Height)+2(width \times height)[/tex]
Substitute the values, we get,
[tex]Area=2(14\times 10)+2(12\times 10)[/tex]
[tex]Area=2(140)+2(120)[/tex]
[tex]Area=280+240[/tex]
[tex]Area=520[/tex]
Thus, Area to be covered by wall paper is 520 ft²
Given cost to cover 1 ft² area by wall paper = $1.53
Then cost to cover 520 ft² area by wall paper = $1.53 × 520 = $795.6
Thus, the cost to wallpaper kitchen at rate of $1.53 per foot² is $795.6
