Question

Two cube of side 4 cm are fixed together find the total surface area of the new solid formed​

Answer 1

Answer:

160 cm²

Step-by-step explanation:

when two cubes are joines together then the resulting solid will be cuboid

length =4 , breadth=8 , height =4

total surface area of new solid=2(lb+bh+hl)

                                                  =2(4×8+8×4+4×4)

                                                  =2(32+32+16)

                                                  =2(80)

                                                  =160cm²
