julie has a box that is 12 by 12 by 4. find the surface area of the open box with a base of that is 12 by 12 and open. find the surface area of the open box if the base was 12 by 4. Which box has more surface area\r
\n" ); document.write( "\n" ); document.write( "base is 12 by 12
\n" ); document.write( "Since the base is 12 by 12 it will have one surface area . there is no lid
\n" ); document.write( "surface area of box = 1*(12*12) +2(12*4)+2*(12*4)
\n" ); document.write( "=144+96+96
\n" ); document.write( "=336 sq. units
\n" ); document.write( ".
