Question

the mass of an iron ball is 312 gram the density of iron is 7.8 gram cm ^-3 find the volume of the ball​

Answer 1

Answer:

here is your answer mate...

Step-by-step explanation:

Given, Mass M = 312 g

Density d = 7.8 g cm-3

Since, d = M /V => V = M / d

Hence, volume of an iron ball V = 312 / 7.8 = 40 cm3

plz plz plz mark me as brainliest plzz...

Answer 2

Answer:

Step-by-step explanation:

Density = mass / volume.

7.8  =    312/V

7.8*V  =  312

V     =  312/7.8

V      = 40cm^3
