Question

Two cubes, each of side 15cm are joined end to end. Find the surface area of resulting cuboid.

Answer 1

Answer:

L X B X H

Step-by-step explanation:

(15 X 15) X 15 X 15

IS THE CORRECT ANSWER

Answer 2

Step-by-step explanation:

Let the side each cube = a= 15 cm

After joining the two cubes it becomes cuboid

Dimensions of cuboid is

Length = a+a = 15+15 = 30 cm

Breadth = b= 15 cm

Height = h= 15 cm

Total surface area = 2(lb+bh+lh)

= 2(30*15 + 15*15+30*15)

= 2(450+225+450)

=2*1125

=2250 square cm.
