A piece of wood that measures 3cm by 6cm by 4cm has a mass of 80g. What is the density of the wood?

1.1 would be the densiry

explanation

p=m/v is the density formula p being density and m being mass and v being volume

multiply 3 by 6 by 4 to get volume of 72

80÷72 = 1.1

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
