What is the density of a piece of wood that weighs 62 grams and displaces 0.525 l of water?
This is clearly a piece of wood that is forcibly submerged since its density would require it to float. So the volume of displaced water should be equal to the volume of the whole piece of wood. Then, density = mass/volume = 62/0.525 g/L = 62/525 g/ml = 0.12 g/ml which is a lot less dense than balsa (0.16 g/ml)!
What is the density of a piece of wood that hasa mass of 25.0 grams and a volume of 29.4cm3?
25/29.4 = 0.85 grams/cm3
Three pieces of wood are needed for a project They are to be cut from a 90-cm-long piece of wood The longest piece is to be 3 times as long as the middle-sized piece and the shortest piece is to be?
87
Jack cut a piece of wood that was 8 feet long into two pieces one piece is three times as long as the other how long in the shorter piece of wood?
Let x be the length measure of the shortest piece of wood, and 3x the length measure of the other piece of wood. So we have: x + 3x = 8 4x = 8 divide by 4 to both sides; x = 2 The length measure of the shortest piece of wood is 2.
What is the density of a block of wood measuring 9cmX2cmX6cm with a mass of 5.4g?
Density = mass/volume = 5.4g/(9*2*6) cm3 = 5.4/108 cm3 = 0.05 g/cm3. Balsa, one of the least dense woods, has a density of 0.16 g/cm3 which is more than 3 times the "density" of your wood! So have you discovered a super-light wood species?
