THis is my second question here in as many years. I need to find out how much lead is contained within an area of 135m x 7.5m if the lead paint used contains 175 micrograms of paint per cm²
Here is my workings. Can anyone please tell me where im going wrong?
Length = 13500cm
Draught = 750cm
Area one side = 13500cm x 750cm
= 10125000cm Area One side
Max Lead of Era paint (highly unlikely)
175 Micro Grams / 1 cm2
1,000,000cm2 of Paint contains 175,000,000 micrograms of lead (175 grams).
One side 10,125,000cm2 / 1,000,000 = 10.125
10.125 x 175g = 1771.875g or 1.77Kg
**Ducks for cover*** - Any help greatly appreaciated.
