Question

two cube each of side 2 cm are glued together. then the total surface area of the resultant cuboib is?

Answer 1

Answer:

given side of a cube, a = 2cm

then, l = 4cm

b=2cm

h=2cm

total surface area of the cuboid= 2(lb+bh+lh)

                                                    = 2(4×2+2×2+42)

                                                    =2(8+4+8)

                                                    = 2×20

                                                   =40cm²
