Answer 2

Given:

• Three cubes having same side 30 cm

According to the question,

• All three cubes are joined end to end.

So, a new cuboid is formed.

To find:

• The volume of the new cuboid formed.

So,

The cubes are joined end to end, one side length of cuboid will be 30+30+30 = 90 cm

And another side (taking as breadth and height) will remain the same.

The formula to find the volume of the cuboid is = lbh units cube.

= 90*30*30

= 81000 cm cube

Hence,

• The volume of the new cuboid is 81000 cm cube.

• The formula to find the total surface area of a cuboid is = 2(lb+bh+hl) units sq.
