i have no answer please help me
To calculate the density, you need to divide the mass of the object by its volume.
The mass is given as 250g.
To find the volume of the rectangular solid, you need to multiply its length, height, and width. The length is given as 6cm, the height is 3cm, and the width is 7cm.
So the volume can be calculated as:
Volume = length x height x width = 6cm x 3cm x 7cm = 126 cm³
Now that we have both the mass (250g) and the volume (126 cm³), we can calculate the density by dividing the mass by the volume:
Density = mass / volume = 250g / 126 cm³
Calculating this, we get:
Density = 1.984 g/cm³
Therefore, the density of the rectangular solid is approximately 1.984 g/cm³.
