Answer:
The cost to wallpaper kitchen at rate of $1.53 per foot² is $795.6
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,

Substitute the values, we get,




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
