Answer:
m=7.475 kg
Step-by-step explanation:
Given that,
The density of tin is 5.75 g/cm³.
We need to find the mass of the object if the volume of the rectangular block is 1.3 L.
We know that,
1 L = 1000 cm³
1.3 L=1300 cm³
The formula of density,
or
m=7.475 kg
So, the mass off the object is 7.475 kg.
