document.write( "Question 1055525: If you have a can of frosting measuring 3\" in diameter and 4\" high, to use on a baking dish with a volume of 256\", would you be able to cover the top with 1/2\" of frosting? If not how many cans would you need? \n" ); document.write( "

You can put this solution on YOUR website!
Knowing the volume of the baking dish is not enough information.
\n" ); document.write( "You need to know the depth of the baking dish also or just the surface area of the baking dish.
\n" ); document.write( "You can calculate the volume of frosting,
\n" ); document.write( " $\"V%5Bavail%5D=pi%2AR%5E2%2AH=pi%2A%283%2F2%29%5E2%2A4=9pi\"$ $\"in%5E3\"$
\n" ); document.write( "Then the volume of frosting needed for the cake would be,
\n" ); document.write( " $\"V%5Bneeded%5D=A%2A%281%2F2%29=A%2F2\"$
\n" ); document.write( "If you had the depth, D, of the baking dish (your units of volume should be cubic inches),
\n" ); document.write( " $\"A=256%2FD\"$
\n" ); document.write( "You could then compare volume needed and volume available. \n" ); document.write( "

\n" );
