1 ft = 12 inches. 1 square foot = 1 ft x 1 ft = 12 inches x 12 inches = 12*12 sq inches = 144 sq inches.
1 ft = 12 in → 5 ft 4 in - 1 ft 6 in = (4 + 1) ft 4 in - 1 ft 6 in = 4 ft (12 + 4) in - 1 ft 6 in = 4ft 16 in - 1 ft 6 in = 3 ft 10 in Alternatively, convert to inches, subtract and convert back: 1 ft = 12 in → 5 ft 4 in - 1 ft 6 in = (5 x 12 + 4) in - (1 x 12 + 6) in = 64 in - 18 in = 46 in = (3 x 12 + 10) in = 3 ft 10 in
1 ft = 12 inches 1/3ft = 12 x 1/3 = 12/3 = 4 inches
12 inches = 1 ft so 840 in = 840/12 ft = 70 ft. Simple!
12 in = 1 ft → 11.5 in x 11.5 in = (11.5 ÷ 12) ft x (11.5 ÷ 12) ft ≈ 0.918 sq ft
12 in = 1 ft → 1 in = 1/12 ft 1 sq in = 1 in x 1 in = 1/12 ft x 1/12 ft = 1/144 sq ft → 1644 sq in = 1644 x 1/144 sq ft = 115/12 sq ft ≈ 11.42 sq ft
1 cubic ft = 1 ft * 1 ft * 1ft 1 cubic ft = 12 in * 12 in * 12 in 1 cubic ft = 1728 cubic inches
1 inch = 1/12 ft = 0.0833... ft
3 ft (12 in = 1 ft)
1 sq ft = 1 ft * 1 ft = 12 inches * 12 inches = 144 sq inches.
1 ft = 12 in → 1 cu ft = 1 ft x 1 ft x 1 ft = 12 in x 12 in x 12 in = 1728 cu in → 681.2 cu in = 681.2 ÷ 1728 cu ft ≈ 0.394 cu ft
1 ft = 12 inches. 1 square foot = 1 ft x 1 ft = 12 inches x 12 inches = 12*12 sq inches = 144 sq inches.
1 ft = 12 in → 5 ft 4 in - 1 ft 6 in = (4 + 1) ft 4 in - 1 ft 6 in = 4 ft (12 + 4) in - 1 ft 6 in = 4ft 16 in - 1 ft 6 in = 3 ft 10 in Alternatively, convert to inches, subtract and convert back: 1 ft = 12 in → 5 ft 4 in - 1 ft 6 in = (5 x 12 + 4) in - (1 x 12 + 6) in = 64 in - 18 in = 46 in = (3 x 12 + 10) in = 3 ft 10 in
1 ft = 12 in 1 sq ft = 1 ft × 1 ft = 12 in × 12 in = 144 sq in → 45 sq ft = 45 × 144 sq in = 6480 sq in.
12 inches = 1 ft so 109 inches = 9 ft 1 inch.12 inches = 1 ft so 109 inches = 9 ft 1 inch.12 inches = 1 ft so 109 inches = 9 ft 1 inch.12 inches = 1 ft so 109 inches = 9 ft 1 inch.
49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.
1 ft = 12 in 1 ft^2 = (12 in)^2 1 ft^2 = 144 in^2
