What is the density of a wooden plank that has a mass of 114 g and a volume of 8m³

The density is the amount of mass per unit of volume of any material. You can find the density by using the formula:


where d is the density, m is the mass and v is the volume

you have the mass and the volume so you just have to replace the variables in the formula with the values they are giving you, like this:


The density of wooden plank is 14.25g/m^3
