Answer:
Step-by-step explanation:
volume of sphere=4/3(π r^3)
Answer:
1.641× 10^-3 pounds/ cubic inch
Step-by-step explanation:
Density= mass / volume
Mass of the material= 9 kilograms
Volume= 7 cubic feet
Density= 9/7= 1.286 kg/ ft^3
Density= 1.286 kg/ ft^3
To Convert to pounds per inch
1 kg/ ft^3 = 0.00128 pound / cubic inch
1.286 kg/ ft^3 = X pounds/ cubic inch
X=( 1.286 × 0.00128)
= 0.0016407087 pounds/ cubic inch
= 1.641× 10^-3 pounds/ cubic inch
Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch
The answer to that problem is 27. You could divide 108 by 4 and get the answer of 27
