How many square meters in 90,000 linear feet of 41.3" wide material?
First, we need to determine the number of square units in the Imperial system. We can choose to do the calculation in feet or inches.
Let's do it in inches first. There are 12" in a foot, so we multiply 90,000 by 12 to get 1,080,000 linear inches. Multiplying this by 41.3", we get 44,604,000 square inches. We can convert this to square feet by dividing the number of square feet by the square inches in a square foot. Since a square foot is one foot by one foot, or 12 inches by 12 inches, there are 144 square inches in a square foot. Dividing our previous answer by 144 will give us 309,750 square feet.
Converting to square metres. An inch is defined as 2.54 centimetres ("cm"). Thus, there are 2.54cm x 2.54cm in a square inch or 6.4516cm^2 in a square inch.
Using the 44,604,000 square inches we got above, and multiplying this by 6.4516, we get 287,767,166.4 square cm. There are 100 cm in a metre, so there are 100cm x 100cm in a square metre. So there are 10,000 square centimetres in a square metre. I get 28,776.7 square metres.
There are 3.280839895 feet in a metre. So there are 3.280839895 x 3.280839895, or 10.76391042 square feet in a square metre. Taking 309,750 square feet and dividing by the 10.76391042 we get 28,776.7 square metres.
