Question

Two cubes each of side 3 cm are joined together. Lateral surface area of new solid ​

Answer 1

Answer:

If two cubes join each other then their lenght get double ,breath remain same and height will also remain same.

so,

Length of cube =2×3 =6

Breath of cube =3

Height of cube =3

Lateral surface area= 2(lb+bh+hl)

=2(6×3+3×3+3×6)

=2(18+9+18)

=2(45)

=2×45

=90cm³
