You can put this solution on YOUR website!
First find the volume of the block of wood.
V+=+L%2AW%2Ah Substitute: L = 10, W = 5, and h = 4.
V+=+%2810%29%2A%285%29%2A%284%29
V+=+200cu.cm.
Density (D) is defined as mass (weight) over volume or gms/cu.cm
D+=+100%2F200gms/cu.cm .Simplify..
D+=+0.5gms/cu.cm.
