1. An object has a mass of 37 gram. After it was dropped to a cylinder the water level rose from 52 mL to 85 mL. What is the density of this object? (Be sure to
include the steps and unit in the answer.) *

 1.12g/ml

Explanation

Ist step

Volume of the object =final volume of water  in the  cylinder -Initial volume of water in cylinder

= 85ml -52ml = 33ml

2nd step

Density = Mass/ Volume

37 g/ 33ml =1.12g/ml

answer is  

loa ≅ lma

to prove that the triangles are congruent using the aas congruence
