## toxicsugar22 2 years ago A block of metal has a volume of 14.0in3 and weighs 5.26lb . What is its density in grams per cubic centimeter?

1. Nurali

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
