Question

the mass of a sheet of metal varies jointly with its area and its thickness a sheet of metal of area 250 cm square and thickness 1 mm has a mass of 200 g find the formula which connect the mass,the area and the thickness

Answer 1

Google "mass,the area and the thickness formula" and read. carefully.

Answer 2

m = ka/t
so, using your numbers,
200g = k(250 cm^2)/(1 mm) = k * 2500 cm
so k = 200g/2500cm = 2/25 g/cm
m = .08a/t

Answer 3

I need an answer

Answer 4

M .08a/t

Answer 5

Joint variation
The mass of a sheet of metal varies jointly with its area and its thickness a sheet of metal of area 259cm^2 and thickness 1mm has a mass of 200gk

Answer 6

That's good

Answer 7

Blah blah blah

Answer 8
