= 12 x 26 sq feet
1 foot = 0.3333 (one-third of a) yard 1 sq foot = 0.3333 x 0.3333 sq yards = 0.1111 sq yards 450 sq ft = 450 x 0.1111 sq yards = 49.99 sq yards
This needs more information to supply a "best" answer. A 12ft by 12ft patio gives a surface area of 16 sq.yds. A yard of concrete is a cubic yard. The number of cubic yards depends on the thickness of the slab, and the size and depth of foundations (if any). This depends on the type of soil and subsoil, and whether you have very cold winters. If you live in a warm area, 3 yards is probably about right. If you are planning to do this yourself, try asking your local building inspector for his advice.
The square feet of a 14ft x 30ft area is420ft2
In one linear yard there are 3feet So in one sq.yard there are 3ft x 3ft = 9 sq.ft Hence 1 sq yd =9 sq.ft. X sq yds = 2.75 sq.ft. Equating x sq yds = 2.74 sq.ft / 9 sq.ft x = 0.30555... sq. yds.
3 feet = 1 yard and so 4 times 5 = 20 square yards
(12ft x 12ft) square =144 sq ft. 12ft x (12 ft square) is 1728 cu ft.
12ft x 12ft =144 ft2
1.) 12ft x 16ft = 192 square feet (1yd = 3ft therefore 1 square yard = 9 sq. ft) 2.) 192 sq. ft. / 9 sq. ft. = 21.33 sq. yds.
14ft x 12ft = 168 sq ft = 15.6 m2
30ft x 90ft = 2,700 sq ft or 250.8382 square meters.
25ft x 12ft = 300 sq ft.
12 x 12 = 144 sq. ft.
72 sq. ft.
348 sq ft
Divide them by 3 because 3 feet = 1 yard
6 x (12 x 12) = 864 sq. feet
