3 ft (12 in = 1 ft)
12 in/ft, so246 in / 12 in/ft = 20.5 ft.
144
12*12 = 144 square feet and its the same as 12 squared
12 in = 1 ft ⇒ 23 in by 67 in = (23 ÷ 12) ft by (67 ÷ 12) ft = 111/12 ft by 57/12 ft ≈ 1.92 ft by 5.58 ft
3 ft (12 in = 1 ft)
12 in/ft, so246 in / 12 in/ft = 20.5 ft.
12 in = 1 ft → 46 in = 46 ÷ 12 ft = 310/12 ft = 35/6 ft ≈ 3.83 ft
12 ft = 4 yds
12 ft = 3,657.6 mm
144
12*12 = 144 square feet and its the same as 12 squared
12 ft * 72 ft * 12 ft = 10368 cubic feet.
12 in = 1 ft ⇒ 23 in by 67 in = (23 ÷ 12) ft by (67 ÷ 12) ft = 111/12 ft by 57/12 ft ≈ 1.92 ft by 5.58 ft
12' * 21 ft = 12*21 sq ft = 252 sq ft.
12 in = 1 ft ⇒ 93 in = 93 ÷ 12 ft = 73/4 ft = 7.75 ft
Assuming the '12' is '12 ft'. Then 12 ft x 20 ft = 240 sq.ft.
