0.762 X 30 = 22.86 sqmt.
After that we convert sqmt. into sqft. on multiplication by 10.76 in sqmt area.
22.86 X 10.76 = 245.97 sqft.

Hence, the area of a fiblerglass screen in square meter is 245.97 sqft.

how did you get the 0.762??

The legal definition of an inch is 25.4 mm or 0.0254 m, exactly.
30" x 0.0254 m/in = 0.762 m exactly

1.34 cubic meter pls covert to square meter...give also the formula how to solve pls...

0.03cubic meter=how many square meters

divide by thickness in meters

I need help!
a concrete contractor estimates the surface area of concrete to be laid on a certain job to be 140m2. The customer has a choice of 75mm thick concrete or 100mm thick concrete. How much extra would he have to pay for the thicker concrete if the costs $220 per cubic meter?

volume = area x thickness but everything has to be in the same units.
Express the thickness in meters, 0.075 m and 0.100 m. Now you can calculate the volume for each case, and take the difference.

What do you mean take the difference?

You need to figure the cost for each thickness, then take the difference to compare.
