Question

Calculate the dencity of a substance whose mass is 800 gram and volume is 40centi meter calculate the volume of a cylinder radius = 3 centi meter and height = 7 centi meter .​

Answer 1

$Answer:\rho = 20g {cm}^{ - 3}$

Given

• mass=800g
• volume=40cm^3

To find

• Denity ([tex]\rho[\rho]

Explanation:

$\rho = \frac{mass}{volume}$

$\rho = \frac{800}{40} = 20g {cm}^{ - 3}$

Additional information

To find density always put mass and volume in Kg/m^3 or g/cm^3.

always use standard units otherwise answer will be wrong
