To calculate the square meters of a duct you must add the total length of the straight duct work plus the loss of length from the elbows. A standard elbows measurement is 15 feet for each elbow with a 4 inch diameter or 20 feet for an elbow with a 6 inch diameter.
The formula for calculating the 90 degree elbow is W+R*2*3.14/4*P=Meter Square . The area is computed by using the formula (W+R)_π/4_P.
1 square metre = 10.7639104 square foot
They are: 1 square meter = 1*1 = 12 meters and 1 cube meter = 1*1*1 = 13 meters
Conversion: cm2 x 0.0001 = square meters
6metres x 8metres = 48 square metres

To calculate the price per square meter, divide the total price by the total number of square meters. For example, if a piece of cardboard with an area of 10 square meters cost 5 dollars, the price per square meter would be (10 m2)/($5), which comes out to be 50 cents per square meter.
Conversion: cm2 x 0.0001 = square meters
6metres x 8metres = 48 square metres
multiply the width by the breadth
That would depend what information you are given. The cost of floor tiling is often already expressed per square meter. If you know the total cost of a certain floor, you can divide by the area to get the cost per square meter.
Square feet x 0.0929 = square metres
