Question

You are redoing your bathroom in marble tile. It is $35.00/sq. ft. You are putting tile on the floor and all 4 walls. The size of your bathroom is 9’ x 10’ with 8’ high ceilings. How much will the marble tile cost ?

Answer 1

Given data:

The size of your bathroom is 9’ x 10’ with 8’ high ceilings

Cost of the marble tile: $35.00/sq. ft.

Area that you will redoing in marble tile is the sum of the area of the 4 walls and the area of the floor.

Area of the floor

$9ft^{}\times10ft=90ft^2$

Area of each 9' x 8' wall:

$\begin{gathered} 9ft\times8ft=72ft^2 \\ \end{gathered}$

Area of each 10' x 8' wall:

$10ft\times8ft=80ft^2$

Then, the area you will redoing in marble tile is:

$\begin{gathered} A=90ft^2+2(72ft^2)+2(80ft^2) \\ A=90ft^2+144ft^2+160f^2 \\ A=394ft^2 \end{gathered}$

As each square feet cost $35.00 find the total cost of 394 square feet:

$35.00/ft^2\times394ft^2=13,790$Then, the marble tile will cost $13,790
