Answer:
The answer to your question is mass = 455.6 grams
Explanation:
Data
Dimensions = 68.6 yd x 12 in x 0.00035 in
density = 2.70 g/cm³
mass = ?
Process
1.- Convert dimensions to cm
1 yd ---------------- 91.44 cm
68.6 yd ------------ x
x = (68.6 x 91.44) / 1
x = 6227 cm
1 in ----------------- 2.54 cm
12 in --------------- x
x = (12 x 2.54) / 1
x = 30.48 cm
1 in -------------- 2.54
0.00035 in ------------- x
x = (0.00035 x 2.54) / 1
x = 0.000889 cm
2.- Find the volume of the foil
V = 6227 x 30.48 x 0.000889
V = 168.73 cm³
3.- Find the mass of the foil
mass = density x volume
mass = 2.70 x 168.73
mass = 455.6 g
