The density of lead is approximately 0.41 pounds per cubic inch. What is the approximately mass, in pounds, of a lead ball that has a 5 inch diameter?

The density of a subtance can be found by dividing the mass of the substance by the volume of the substance. The table gives the density of several pure metals in grams per cubic centimeter. Suppose a rectangular sheet of a pure metal weights about 515.9 grams and measures (1)/(4) inch by 2 inches by 8 inches. Assuming the sheet is one of the metals in the table, which metal is it? (There are approximately 2.54 centimeters in 1 inch.)

One method of calculating the approximate age , in years, of a tree of a particular species is to multiply the diameter of the tree, in inches, by a constant called the growth factor for that species. The table above gives the growth factors for eight species of trees. According to the information in the table,what is the approximate age of an America nelm tree with a diameter of 12inches

A solid, cone-shaped lead crystal paper weight has a height of 5 centimeters and a base diameter that is 20% larger than the height. If the density of lead crystal is 3.1g"/"cm^(3) , what is the approximate mass of the paperweight? Round your answer to the nearest gram.

The weight of an object on or beneath the surface of the moon varies directly as its distance from the center of the moon, assuming that the moon has uniform density . The radius of the moon is approximately 1,080 miles. If an object weighs 60 pounds on the surface of the moon, how far beneath the surface, in miles , would it have to be to weigh 50 pounds ?
