Question

two cubes each of 10cm Edge are joined end to the end find the surface area of the resulting cuboid

Answer 1

here is your answer.......

Answer 2

Answer:

 1000 cm²

Step-by-step explanation:

Side of cube given = 10 cm

When two cubes are joined end to end the length of cuboid we get

Length of fist cube + length of second cube  = 20 cm

Height and Width of resulting cuboid remains same as no cube was put above any and behind any of them

So dimensions of Resulting Cuboid = 20 cm × 10 cm × 10 cm

Now, Surface Area of Cuboid = 2(LB + BH + HL) unit²

                                                 = 2(20×10 + 10×10 + 10×20) cm²

                                                 = 2 ( 200 + 100 + 200) cm²

                                                  = 2 × 500 cm²

                                                = 1000 cm²
