Given:-
There are two types of log to measure the density.
Pine log of radius 5-inch and 30-inch long.
Oak board that is 5.5 inch long and 1.5 inch thickness and 3 feet long.
To find the shapes which can be used.
The pine long is round in shape so the shape formed in pine log is CYLINDRICAL SHAPE.
Oak board is 5.5 inch long and 1.5 inch thickness and 3 feet long so the shape formed will be CUBOID.
So the required solutions are CYLINDER AND CUBOID.
