a block of metal has the dimensions of 2cm, 2cm,and 1cm. the block has a mas of 400g.what is the density

First find the volume, lxbxh = 2x2x1 = 4 cubic cm, Now, Density = Mass/Volume = 4oo/4 = 100g/cubic cm
To find the density of the block, we need to use the formula:
Density = mass / volume
First, let's calculate the volume of the block. Since the dimensions are given in centimeters, we need to convert them to cubic centimeters (cm³):
Volume = length × width × height
In this case, the length is 2 cm, the width is 2 cm, and the height is 1 cm. Thus, the volume is:
Volume = 2 cm × 2 cm × 1 cm = 4 cm³
Next, we need to convert the mass from grams (g) to the standard unit of kilograms (kg) since the formula requires it:
Mass = 400 g = 400 / 1000 kg = 0.4 kg
Now, insert the values into the density formula:
Density = 0.4 kg / 4 cm³
Simplifying, we get:
Density = 0.1 kg/cm³
Therefore, the density of the block is 0.1 kilograms per cubic centimeter (kg/cm³).
