Question

DIRECTIONS for the question: The question below is followed by two statements marked I and II. Mark as your answer.

What is the surface area of the cuboid? (in m² )

I. Each dimension (in m) of the cuboid is an integer less than 23. The volume of the cuboid is 154 m³.

II. The length of the cuboid is 7m.

1. If statement A alone is sufficient but B is not sufficient
2. If statement B alone is sufficient but A is not sufficient
3. If both statements A and B are needed
4. If each statement A or B alone is sufficient
5. If both of them together are not sufficient

Answer 1

Correct Answer - Option 1 : If statement A alone is sufficient but B is not sufficient

Calculation:

From statement l

⇒ Each dimension of the cuboid is an integer less than 23. The volume of cuboid is 154 m³

⇒ Hence "statement l" alone is sufficient to answer the question

From statement ll

⇒ The length of the cuboid is 7cm

⇒ Hence statement ll not sufficient to answer the question

∴ The required result will be "If statement A alone is sufficient but B is not sufficient"

The surface area of cuboid = 2 × (lb + bh + hl), Where l = Length of the cuboid, b = Breadth of the cuboid, h = Height of the cuboid

The volume of cuboid = l × b × h, Where l = Length of the cuboid, b = Breadth of the cuboid, h = Height of the cuboid.
