Question

The height of a storeroom is 10.5 ft, the maximum number of boxes with height
11 inch that can be stacked one over the other in the storeroom is .

• A. 9
• B. 11
• C. 12
• D. 10

Answer 1

The correct option is B 11

Given:
Height of room = 10.5 ft
= 10.5 × 12
= 126 in
Height of box = 11 in

Let the number of boxes stacked in the room be x
so,
11x ≤ 126
$⟹$ x ≤ $\frac{126}{11}$

$⟹$ x ≤ $11\frac{5}{11}$

Hence, the maximum number of boxes that can be stacked one over another in the storeroom is 11.
