harold is a woodworker and is interested in finding the density of two different types of wood. he bought a pine log that has a 5-inch radius and is 30 inches long. the weight of the log is approximately 42.63 pounds. he also has an oak board that is 5.5 inches wide, 1.5 inches thick and 3 feet long. the board weighs approximately 8.05 pounds.
part b
what is the density of the pine log? show your work.
part c
what is the density of the oak board? show your work.
part d
if you had a block of each type of wood with the same dimensions, how would their weights compare? explain.
part e
water has a density of about 0.0361 pounds/cubic inch. you might know that wood floats on water. what can you conclude about the densities of objects that float and the densities of objects that do not? review your results from parts b and c before deciding.
