10 ft 8 in * 8 ft 4 in = 88.88.. sq feet = 8.2580 sq metres
If the question refers to 2" x 4" then there are 2 x 4 = 8 sq in. If the question refers to 2' x 4' (i.e. the lengths are in feet) then there are : 2 x 12 x 4 x 12 = 1152 sq in
1 in = 2.54 cm (exactly) ⇒ 4 sq in = 4 x (1 sq in) = 4 x (1 in x 1 in) = 4 x (2.54 cm x 2.54 cm) = 4 x 6.4516 sq cm = 25.8064 sq cm ≈ 25.8 sq cm
6' * 4' = 72" * 48" = 3456 sq inches
1 in = 2.54 cm (exactly) 1 sq in = 1 in x 1 in = 2.54 cm x 2.54 cm = 6.4516 sq cm ⇒ 4 sq in = 4 x 6.4516 sq cm = 25.8064 sq cm ≈ 25.81 sq cm
4 sq feet
1 foot = 12 inches So 4 sq ft = 4*(1 ft x 1 ft) = 4*(12 in x 12 in) = 4*144 sq inches = 576 sq inches.
36" X 4" = 144"/sq
10 ft 8 in * 8 ft 4 in = 88.88.. sq feet = 8.2580 sq metres
If the question refers to 2" x 4" then there are 2 x 4 = 8 sq in. If the question refers to 2' x 4' (i.e. the lengths are in feet) then there are : 2 x 12 x 4 x 12 = 1152 sq in
1 in = 2.54 cm (exactly) ⇒ 4 sq in = 4 x (1 sq in) = 4 x (1 in x 1 in) = 4 x (2.54 cm x 2.54 cm) = 4 x 6.4516 sq cm = 25.8064 sq cm ≈ 25.8 sq cm
12 x 16 = 192 sq ft = 27,648 sq inches (192 x 144 sq in/sq ft) each tile = 4 x 4 = 16 sq in you need 27648/16 = 1728 tiles
6' * 4' = 72" * 48" = 3456 sq inches
1 in = 2.54 cm (exactly) 1 sq in = 1 in x 1 in = 2.54 cm x 2.54 cm = 6.4516 sq cm ⇒ 4 sq in = 4 x 6.4516 sq cm = 25.8064 sq cm ≈ 25.81 sq cm
There are 144 sq. inches in a sq. foot, so 144 x 20 = 2880 sq. inches
110 inches x 60 inches = 6600 square inches / (144 sq in / sq ft) = 45.833 sq ft
= (9 + 4/12) x (12 + 7/12) sq feet
