there are 29 walls. each wall 10x50 ffet. you have can of paint 400 square ft. how many cans need, estimated v\n25-35\n35-45\n45-55\n55-65

36.25 cans, not figuring for waste or spillage, so answer would be 35-45. More than likely you will have to put two coats to get a good  even coverage., so you may want to double this figure.***

Ya i agree to ask around first, here is depends one crew will go in for only 3.50 sq ft. were the best goes for 5.50 sq ft.  Are you doing the indise or outside? The inside can get alittle complicated with trim and different colors. Its a great money making job. We only do the drywall and the different custom textures. We do ok, but thats a seperate 1.00 - 1.25 sq ft. and then we have another crew hang the sheetrock so that an extra whatever per sheet. Some painters and drywall crew charge by the board. We do it by the sq ft. \n\nbut if its a turnkey job doesnt that mean your responsable for hanging, tape float and texture, and painting.  Its not that bad its a good job. Good luck!

You can find how many square feet the kitchen is by multiplying 18*15. This equals 270 sq. feet.  (The * means multiplication)\n\nSince each tile is one square foot, you will need 270 tiles.  Multiply the number of tiles by $18, and thats the cost to cover the floor.\n\nEquations:  \nLength * Width\n\n(Number of Tiles) * (cost per tile)

36.65 sq ft = 36 sq ft + 93.6 sq in\n\nYou multiply 0.65 sq ft x 144 to get sq in, because as you already used it, 144 sq in = 1 sq ft

Your rectangle (in feet) comes out to 8.2' x 19.7'.  Each row needs 8 tiles plus one strip of 1x6 tiles (if your tile sheet is 2" tiles in a 6x6 configuration).  You will have 19 full rows of tile in the other direction, plus 1/2 sheets of 3x6 tiles.  All in all, you will use 152 FULL tiles, plus 1.3 sheets for the 1x6 strips and 9.5 sheets for the 3x6 sheets.  All in all, you will have 12 tiles left over (2 1x6 strips) if everything lays out properly.\n\nTotal number of tile sheets needed: 163\nTotal left over: 12 2" tiles.

Since the total distance is 750 miles and you need a gallon of oil for every 25 miles, 750 divided by 25 equals how many gallons you need which is 30.\n\nIf each gallon costs 3.50$, then times that by 30 since you need 30 gallons of oil. So thats 3.50 times 30 which is 105.00$\nSo the answer is $105.00.

If you subtract the 0.3 sq. inches you will get the minimum.\n50.25 - 0.30 = 49.95 sq. inches\n\nAnd if you add the 0.3 sq. inches you will get the maximum.\n50.25 + 0.30 = 50.55 sq. inches

now, the number of chickens are 7*7=49, since there are 7 chickens in each sack and there are 7 sacks.\nthe number of chicks are 7*7*7=343, since each chicken has 7 chicks, each sack has 7 chickens and there are 7 sacks.\nthe nubmer of people are 7.\neach person has 2 feet, each chicken has 2 feet and each chick has 2 feet.\nnow total no. of feet= 2*(7+343+49)\n                                =2*399=798\nso, there are a total of 798 feet

Total area = 120\nArea of picture = 8*10 = 80\nArea of border = 120 - 80 = 40\n\nArea of border\n= Area of both - Area of picture\n= (8+2x)(10+2x) - 80\n-- where x is the border width\n-- 2x because there are borders on both sides of the picture\n\nSo\n(8+2x)(10+2x) - 80 = 40\n80 + 16x + 20x + 4x^2 - 80 - 40 = 0\n4x^2 + 36x - 40 = 0\nx^2 + 9x - 10 = 0 --- div. both sides by 4\n(x+10)(x-1) = 0\nx = -10 or 1\n\nBut as this is length, -10 is not applicable.\n\nSo the width of the border is 1 unit.

0 with 4 faces, 24 with 3 faces, 60 with 2 faces, 48 with 1 face and 12 with 0 faces.  \nNote, this is if the 3 cubes were not touching each other.  I made an assumption when you said that they were originally 3 separate cubes.  I believe, after reading the second answer, that I made an incorrect assumption since you said "total volume".  If the 3 cubes were touching each other when painted, I am wrong.

ANSWER : 25 square units.\n\n---------------------------------\n\nFirst off, draw a picture. \nSo, you have one point on the (0,0), one on the x-axis, one on the y-axis, and one on the diagonal line.\n\nLet's call the length of the horizontal line segment of the rectangle w.\n\nThe other side will then be (10-w).\n\nSo, the area of the rectangle is A = w*(10-w).\n\nIf you graph this, there is a maximum at the point (5,25), so 25 is the max area.\n\nTo verify this, take the derivative of A with respect to w, and set equal to zero.\nA' = 10 - 2w = 0\n2w = 10\nw = 5\nA = 5(5) = 25

If it takes 5 people t days to do the house, then each day, 1/t of the house is painted.  If 5 people paint 1/t part of the house, then the rate at which each person paints 1/5t part of the house per day.  If 6 people take t - 8 days to paint the house, then each day 1/t-8 part of the job is done.  Since there are 6 people, each person paints 1/6(t-8) part of the house.  If we assume that each painter works at the same rate, then 1/5t = 1/6(t-8).  If we take reciprocals we get 5t = 6(t-8) and t = 48 for 5 people and 40 days for 6 people.
