A 5 cm cube made out of black wood was completely painted blue. It was cut into 1cm cubes. How many of these small cubes haveonly 1 blue face? |

Answer» TOTAL NO OF 1 cm CUBES = 5 x 5 x 5 = 125 OF THIS ON EACH OF THE EXTERNAL SLICE 3 x 3 = 9 CUBES WILL HAVE ONLY ONE SIDE PAINTED. OF THE REMAINING 4 WILL HAVE PAINT ON THREE SIDES AND 12 WILL HAVE PAINT ON TWO SIDES. TOTAL NUMBER OF CUBES THAT WOULD HAVE PAINT ON ONLY ONE SIDE = 6 x 9 = 54 hope it helps stay safe and happy holi |
