a block of wood 3.0 cm on each side has a mass of 27 grams what is the density of this block thanks
To find the density of an object, we need to divide its mass by its volume. In this case, we have the mass (27 grams), but we need to calculate the volume of the block.
The volume of a rectangular block can be calculated by multiplying its length, width, and height. In this case, all sides of the block are given to be 3.0 cm. So, the volume (V) can be found as:
V = length x width x height
= 3.0 cm x 3.0 cm x 3.0 cm
= 27.0 cm³
Now, we can calculate the density (D) using the formula:
D = mass / volume
= 27 grams / 27.0 cm³
Dividing 27 grams by 27.0 cm³, we get the density of the block:
D ≈ 1.0 grams/cm³
Therefore, the density of the block is approximately 1.0 grams/cm³.
The formula for density is p = m/v, where p is density, m is mass, and v is volume. First, you would figure out the volume by:
V = 3 cm * 3 cm * 3 cm
V = 27 cubic centimeters
Plug everything that you know into the formula:
p = 27g / 27cm^3
p = ? g/cm^3
Hope this helps! :)
