a room 24 ft long 18 ft wide and 9 ft tall how many sq yards of wallpaper is needed for 4 walls in the room?
822867
144 yards for the long sides of the room, and 108 yards for the shorter walls.  252 yards total.

Think of a "foot ruler" (12 inches) - three (3) of those would equal 1 yard (that would be 36 inches or a "yard stick").  So if you are given 65 feet that would equal 21.6666 (or perhaps 21 and 2/3d) yards.  Divide 65 feet by 3 feet.

width = 5 \nlength = 12

12 x 16, that will equal square feet (192)\njust measure length times width to calculate square footage

figure it out...\n                Area\n144 sq. inches = 1 sq. ft\n9 sq. feet   = 1 square yard\n4840 sq. yards  = 1 acre\n8 furlongs = 1 mile  \n640 acres      = 1 square mile\n5280 feet = 1 mile   \n1 sq.mile    = 1 section\n1760 yards = 1 mile  \n36 sections   = 1 township

let us assume that you are trying to measure a room :\n\nso you check linear lenghth in one side and then linear length in other side and let us call them as length and width \nassume: \nlength =12 ft\nwidth =10 ft\n\nthen area= length xwidth \nso \narea=12x10=120 square feet.\n\nlinear is  distance \nsquare feet is area.

A = lb = 98 in² (l = length and b = width, both in inches)\nSo b = 98/l\nWorking area W = (l - 8)(b - 4)\n= lb - 4l - 8b + 32\n= 98 - 4l - 8b + 32\n= 130 - 4l - 8b\n= 130 - 4l - 784/l\n\ndW/dl = - 4 + 784/l²\n= 0 for stationary points\nSo 4 = 784/l²\nie 4l² = 784\nThus l² = 196\nl = √196 (ignoring negative result)\n= 14 inches\nd²W/dl² = - 2 * 784/l³ < 0 when l = 14 so area is minimised when l = 14\n\nWhen l = 14 b = 7 (lb = 98)\nSo the dimensions to minimise paper used is 14 inches X 7 inches

12in × 12in is the same as  1ft × 1 ft. That makes things easy.\n\n(12ft ×14ft) - (2ft × 4ft) = 160 ft²\n\nIf this is just a math problem for homework, then that is your answer.\n\nIn real life, you will want to get more than you need, for cutting and in case of defects, accidents etc. So in reality you would probably want 180 tiles for a 160 ft² project.

You need to buy nine yards to cover 231 square feet to 4 inches depth: Volume = depth x area = 4/12 x pi x 42^(2) / 8 = 231 cubic feet, assuming the semi circular driveway is half of a circle with diameter of 42 feet. There are 27 cubic feet in a cubic yard (3x3x3) so 231 cubic feet is about 8.55 cubic yards, which I rounded up to nine. More or less about ten pickup trucks full of topsoil.\n\nA bag of grass seed that covers 1000 square feet will allow you to seed the patch (231 square feet) three times with some left over.

First let us calculate the net area of the 4 walls:\n2(36*5)+2(24*5) = 600sq m\nCalculate the area of doors and windows:\n2(3*3) + 4(1.2*1) = 22.8 sq m\nThen to get the area of the walls to be painted:\n600 - 22.8 = 577.2 sq m\nthe rate of white washing the walls is 7$/sq m therefore the cost will be:\n577.2 * 7 = 1177.3 $

a square yard is basically a square that is 1 yard on each side or 3 ft on each side. 1 yard=9 square feet (3x3)
145526
Length times width. A square measuring 2 feet by 2 feet is four square feet.

This is pretty easy. You know the yard is square, and you know its area. So you can find the length of one side by taking the square root of the area, which is 120 feet.\n\nSince you want to surround the yard with fencing on all four sides, you must buy 4 * 120 = 480 feet of fencing.\n\nThe total cost is then 480 * 8 = $3840.00

You can't do the math to determine this answer.  You can not convert from cubic yards to square feet. \n\nHowever, if you are trying to convert from square yards to square feet the answer would be there are 9 sq. ft. in 1 sq. yd.  (You have a square 1 yard by 1 yard, in one yard there are 3 feet, so you have a square that is 3 feet by 3 feet which is 9 square feet.)\n\nIf you are converting from cubic yards to cubic feet the answer would be 27 cubic feet are in 1 cubic yard.  (You have a cube that is 1 yard by 1 yard by 1 yard, there are 3 feet in a yard, so you really have a cube that is 3 feet by 3 feet by 3 feet which is 27 cubic feet.)\n\nHope this helps.  Good luck.  :)

4 walls -> 5m x 2.5m x 4 = 50 sq.m\nRoof    -> 5m x 5m       = 25 sq.m  total 75 sq.m\n\nLess for 1 door -> 0.9m x 1.8m = 1.62 sq.m\nless for 2 windows 1.2m x 1m x 2 = 2.4 sq.m total 4.02 sq.m\n\nArea to be painted 75-4.02 = 70.98 sq.m\nNow just multiply with the rate

since 24 inches equals 2 feet divide 44 by 2 which would give you 22 strawberry plants needed

A square foot is an actual square measuring 12 inches in length on each of it's four sides.
