Science questions!? (easy sixth grade questions!?)?

Question

how do you find the...

-Mass of an object

-Volume of a regular solid

-Volume of an irregular solid

-Density of an object

-the temperature of a liquid

-the speed of a moving object

and how do you...

-Convert cm to m and m to cm.

Answer 1

-To find the volume of a regular solid, you do:

Height x width x depth

& with an irregular solid, you have to split it into regular solids

- Density = Mass ÷ Volume

- You divide by 100 to convert cm to m and multiply by 100

   to convert m to cm.

Hope that helps

Answer 2

-Weigh it

-Take the dimensions of it and simply calculate it

-Use the Archimedes principal

-First find the mass and volume and then use the form dens=mass/volume

-Using a thermometer

-Using a velocity machine or counting how much distance went during a certain period of time.  Speed= distance/time

-  cm /100 = m

     m x 100 =cm
