Algebra.Com's Answer #40532 by rcmcc(152)![]() ![]() You can put this solution on YOUR website! in a rectangular prism there is always 2 opposite sides that have the same area, \n" ); document.write( "to find the surface area, the sides, multiply by LxW and multiply by 2. \n" ); document.write( "since there are 3 sets of sides we have to make 3 calculations and add the together.\r \n" ); document.write( "\n" ); document.write( "LxW is one set \n" ); document.write( "LxH is another set \n" ); document.write( "WxH is the third set\r \n" ); document.write( "\n" ); document.write( "set 1=(2)x(8)x(5) \n" ); document.write( "set 1 surface area is 80cm squared \n" ); document.write( "set 2=(2)x(8)x(3) \n" ); document.write( "set 2 surface area is 48cm squared \n" ); document.write( "set 3=(2)x(5)x(3) \n" ); document.write( "set 3 surface area is 30cm squared\r \n" ); document.write( "\n" ); document.write( "to find the total surface area, add the numbers together.\r \n" ); document.write( "\n" ); document.write( "the total surface area of the cube is 158cm squared \n" ); document.write( " |
