 Title: areas and volumes of solids Post by: IKAY on May 10, 2008, 09:28:20 pm hi there!could you pls.help me find the solution for this prob?q)find the mass of a lead ball having a diameter of 15cm.a cubic metre of lead has a mass of 11 422kg. Title: Re: areas and volumes of solids Post by: Fu-Kwun Hwang on May 10, 2008, 10:50:36 pm Do you know the definition of density? If you find the denisity of lead and calculate the volume of object, you will find the mass of the object. Title: Re: areas and volumes of solids Post by: schoolreviews on October 10, 2011, 02:00:59 pm The density  of a material is  mass per unit volume. p=m/vBased on this  you can  find it.  Title: Re: areas and volumes of solids Post by: diinxcom on December 14, 2014, 06:03:59 pm Mr. Hwang has reply...I go back-*-
