Question

A block of metal has a volume of 14.0in3 and weighs 5.26lb .

What is its density in grams per cubic centimeter?

nurali · Answer

1 pound = 453.59237 grams 
so 5.26 pounds = 2385.896 grams 

1 inch cubed = 16.387064 centimeters cubed 
so 14 inches cubed= 229.418 cm cubed 

D=M/V
D=2385.896/229.418
D=10.39 gram / cubic centimeter
