Roy Harris · Answer 1

Find the density of both

Object One

Volume = 1.05^3 cm^3 = 1.158 cm^3

Mass = 14.32

Density = mass / volume

Density = 14.32 / 1.158

Density = 12.37 g/cm^3

Object Two

The density for this object is found exactly the same way. Just use the numbers given to you.

Density = 11.43 grams / cm^3

Conclusion

Since you trust your gives to 3 places, it does not look like these two cubes are made of the same material.

Answer: Not the same material <<<===
