![]() Will fit onto this bathroom floor- now the significant The final answer- we care about how many tiles Let me write thisĪnd it actually just keeps going- feet squared. But this is going toīe our final answer, so here we do care aboutĪctually just keeps going. It would be the area of theīathroom, so 121.907 feet squared, divided by theĪrea of the tile, divided by 1.07 feet squared. Tiles fitting in bathroom, in the floor of this bathroom. Guess we could say my bathroom, or tiles in the bathroom, So what you do is you keep itĪs kind of the full number. More error into your calculation than you'd want to. If you round here, you actually will introduce And so the generalįigures until you are done with your calculation,Įspecially if you're just doing a bunch of How many of these tiles will fit into this area. Would be OK if this is all you were lookingįor, if the final answer you were looking for was Say, look, my area should not have more than three I have three significantįigures over here. Temptation right here to say, look, I had four This is equal to 121.907įeet squared, or square feet. I could go a littleīit more to the right. Me scroll over a little bit to the right. And so the area of theīathroom floor, so floor area is going to be equal toġ0.1 feet times 12.07 feet. Is I would figure out the area of this bathroomįloor and then divide by the area of the tiles. To figure out how many tiles can fit on this bathroom floor. Slightly higher precision, so 12.07 feet. Of my floor- I'll just make up a number- is 12 point-Īnd for whatever reason, I was able to measure this with My bathroom to be- I'll do it in feet, now. Kind of legit here, I have to round this to ![]() Significant figures, I could have only have To come up with that product or quotient. Number of significant digits in whatever you are using Product or your quotient cannot be any more than the least There's the dividend, and there's the quotient. You multiply or divide, the significant figures in your Significant figures than either of the numbers Or this calculation that'sĭerived from my measurements- I make sure that it has no more Was able to measure the area to the nearest centimeter. Is that when I give you this thing that hasĪll of these numbers behind the decimal pointĪnd all of these what we now know to be significant Meters, which gives us meters squared or square meters. Hand, but let me just get the calculator out just to make The length times the width, so it would be 1.69 And you were toĪsk me, Sal, what is the area of your carpet? And so I'd just do the To measure the width here as 2.09 meters. To the nearest centimeter, I get it to being 1.69 meters. Meter stick, I'm able to measure the carpet Think about a situation where significant figures Significant figures we're even dealing with, let's The 2 extra tiles in this account are probably due to the fact that I ignored the last tile at the bottom right corner.ĭecent understanding of how to figure out how many Thus, you will have to use, not 3 tiles split into threes as predicted, but 11 tiles for the 10.8 sqft space in the last column i.e. The last tile is consumed by the 0.1 x 12.07 = 1.207 sqft area at the bottom, accounting for the last missing tile.ĩ rows of 11 tiles can also span 9.63 feet breadthwise but only 11 feet lengthwise, thus spanning 0.77 feet less than predicted (leaving 1.07 feet). This extra space will mean that you will need 10, not 5 tiles for the last row accounting for 5 of those 6 missing tiles. The left over area at the bottom would be 1.01 x 12.07 = 12.19 sqft. Thus, 9 rows of 11 tiles each may 11.77 feet lengthwise and thus not 9.63 but 9 feet breadthwise, leaving not 0.47 feet to be spanned but 1.1 feet. A tile having an area of 1.07 square feet has dimensions of 1.07 feet x 1 foot, meaning that at any one time, it can cover 1.07 feet along one, not both, of length and breadth. I think you might be making a small mistake in the dimensions of your tile.
