Calculate the density of a block of 400g and volume 0.02m3

The density of the block will be 20000 g/m³

Explanation

Given that, mass of the block is 400 g  and Volume is 0.02 m³

Formula for Density is:  

So, plugging the values of and into the above formula, we will get.....

So, the density of the block will be 20000 g/m³

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:
