< Chapter 1 Quiz Exercise 1.120 Part A Use the denity of aluminum to find the radus of the sphere in inches in 0

Answer 1

Density of Al = 2.70 g/cm³

Means,

Volume of 2.70 g. of Al = 1 cm³

then,

Volume of 85 g. of Al = 85 * 1/ 2.70 = 31.5 cm³

But,

1 inch = 2.54 cm

1 cm = 1 / 2.54 inch

1 cm³ = ( 1 / 2.54 ) 3 inch³

1 cm³ = 0.0610 inch³

Then, 31.5 cm³ = 0.0610 * 31.5 = 1.92 inch³.
