An object has a mass of 18 g and its volume is 2 centimeters cubed. calculate the density.

To get the density, we divide mass over volume

density = mass/volume

density = (18 grams)/(2 cubic centimeters)

density = (18/2) grams per cubic cm

density = 9 grams per cubic cm

This means one unit block has 9 grams of this material. By "unit block", I mean 1 cm by 1 cm by 1 cm (volume = length*width*height = 1*1*1 =1)

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

4

im pretty sure it's 4 beacsue 8/2 equals 4
