Question

Three cubes each of side 6 cm are joined end to end. The surface area of resulting cuboid is :
432 sq.m , 480 sq.m , 216 sq.m
504 sq.m​

Answer 1

Answer:

584 sq.m

Step-by-step explanation:

When 3 cubes join

Length = 18

Breadth = 6

Height = 6

Surface area = 2(lb + bh + lh)

                      = 2(18*6 + 6*6 + 18*6)

                      = 2(128 + 36 + 128)

                      = 2 * 292

                      = 584 sq.m
