Question

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

Answer 1

Answer:

15*15*30

225*30

7750cm Square

Answer 2

Answer:

6750 cm cube(3)

Step-by-step explanation:

As two cubes are joined,

i. e. breadth and height of the cube remains as it is but only its length will change,

Two cubes are charged to cuboid

So for cuboid,

b = h = 15 cm,

l = 15 + 15 = 30 cm,

Volume of cuboid = l * b * h

= 30 * 15 * 15

= 30 * 225

= 6750 cm cube
