Aluminum has a density of 2.70 g/ml what is the volume of an aluminum block that has a mass of 55.67 kg

              Volume =  20618 mL   (Or)     Volume =  20.61 L

Data Given;

                   Density  =  2.70 g/mL

                   Mass  =  55.67 Kg  =  55670 g  

                   Volume  =  ?

Formula Used;

                   Density  =  Mass ÷ Volume

Solving for Volume,

                   Volume  =  Mass ÷ Density  

Putting values,

                   Volume  =  55670 g ÷ 2.70 g.mL⁻¹

                   Volume =  20618 mL

Or,

                  Volume =  20.61 L

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
