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.
(a) Find the formula which connects the mass Mg,the area A cm square and the thickness t mm.
(b) Hence find the mass of a piece of metal of area 400 cm square and thickness 3 mm

Answer 1

m = kat
200 = k*250*1

Now you can figure k, and thus answer the questions

Yes

Answer 4

the mass of a sheet of metal varies jointly with its area and its thickness.a sheet of metal if area 250cm² and thickness 1mm has a mass of 200 g.

Answer 5

M=ka/t
200g=250cmk/250
K =0.8
