Spanish mahogany has a density of 53lb/ft^3. What is the approximate weight (in pounds) of a piece of mahogany that measured 10in x 12in x 14in?

Answer 1

mass = volume x density
The density is given. The volume can be calculated from 10 x 12 x 14 which gives you the volume in cubic inches. You must then change this to cubic feet. There are 1728 cubic inches in a cubic foot. Post your work if you get stuck.
