(but not on the ceiling). The length of his room is 10 feet the width is 14 feet and the height is 12 feet. If each tile is 1 foot long and 1 foot wide how many tiles does he need?

Two walls are 14 ft x 12 ft = 168 square ft (or tiles) each wall or 2*168 = 336 for both walls.
Two walls are 10 ft x 12 ft = 120 square ft (or tiles) each wall or 2*120 = 240 for both walls.
336 + 240 = 576.
So you may need 578 tiles to cover all four walls.
In reality, the thickness of the tile at the corner reduces the amount of tile needed at the adjacent wall by the amount of the thickness. I.e. if the tile is a quarter inch thick and goes all the way to the wall, than its adjoining wall will need 1/4 inch less tile, or 1/2 inch less tile from both sides.
Most tile installations include a separation of about 1/8 to 1/4 inch between tiles which is filled with grout. That also reduces the total number of tiles needed.
Since during installation, you don't know exactly what will happen, and you need to consider the possibility of mishaps such as dropping tiles and breaking or mis-cutting, it is a good idea to get extra tiles at the beginning and return excess tiles when done, or keep a few for future replacement.

Do a square have length width and height?
A cube (3D) has length, width and height. A square (2D) drawn on a piece of paper only has length and width - in the case of a square, all sides have the same length.
When writing length width height what come first?
It doesn't matter but Length * Width * Height is usually how people say it :D
How do you find length in the area of rectangle and its width?
multiply length times height times width
Do you include ceiling height when measuring the square feet of a room?
No, just length X width.
Does a point have length and width but no height?
No. It has NO length, NO width, NO height. Only a position.No. It has NO length, NO width, NO height. Only a position.No. It has NO length, NO width, NO height. Only a position.No. It has NO length, NO width, NO height. Only a position.
How do you find the height using the length the width and the volume?
height*length*width = volume Divide both sides by length*width to find the height: height = volume divided by length*width
How do you find width when volume height and length are given?
You really should know how to answer that question.Volume = (length) x (width) x (height) .Length = (volume) / (width x height)Width = (volume) / (length x height)Height = (volume) / (length x width)
How do you do area with width height and length?
You multiply the width or length by the the height.
What is the formula for finding the length if you have the volume height and width?
volume = length*height*width Rearrange the formula: length = volume/height*width
How do you find out height width and length of a square?
You measure the height, width, and length.
Solid figures that have length width and height?
All solid figures have length, width and height and, conversely, if a figure has length, width and height then it is a solid figure.
How do you work out a square prism width and height when given volume and length?
Volume = Length x Width x Height. If the prism is square, then either Height = Width or Height = Length In the first case, Volume = Length x Width2 and so Width = sqrt(Volume/Length) and Height = Width. In the second case, Volume = Length2 x Width and so Width = Volume/Length2 and Height = Length.
What are the factors of the polynomial when you factor with tiles the height and width of the rectangular?
if a is number of tiles high and b is tiles wide then, (x+a) = height and (x+b) = width so the polynomial is (x+a)(x+b).
What is the number representing the linear dimension of an object is referred to as?
Length (breadth, width or height are also used).Length (breadth, width or height are also used).Length (breadth, width or height are also used).Length (breadth, width or height are also used).
What would be the width of a a ceiling covered by 49 square tiles when the tiles are 4 square feet?
Type your answer here... You first need to make an assumption that both the tiles are square and the ceiling is square, otherwise there are any number of possible answers. Each tile would therefore measure 2 ft x 2 ft. The ceiling would be 7 tiles x 7 tiles. The width of the ceiling would be 7 tiles x 2 feet = 14 feet.
