Akitchen is 12 ft x 14 ft x 10 ft, how much will it cost to wall paper at $1.53 per foot2

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,

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
