Question

side of a cube is 1 cm , what is the TSA formed by joining 2 such cubes is ?​

Answer 1

Answer:

I think 2 cm^2

Step-by-step explanation:

(1×1)+(1×1)

=1+1

=2

Answer 2

Joining 2 cubes gives us a cuboid

Dimensions of cube= 1cm edge

Dimensions of cuboid= 2cm x 1cm x 1cm

                                    = lxbxh

TSA of cuboid= 2(lb+lh+bh)

                       = 2(2+2+1)

                       =2x6

                       = 12cmsq

Hence the TSA of the formed figure is 12cm sq.
