Question

How many ladders each of length 6 metres should be stacked end to end to achieve a total height of 48 metres?

• A. 6
• B. 7
• C. 8
• D. 9

Answer 1

The correct option is C 8

Length of each ladder = 6 metres

To find the number of ladders needed to reach a height of 48 metres, we need to divide 48 metres by 6 metres.

$\frac{48\text{metres}}{6\text{metres}}=8$

Thus, 8 ladders each of length 6 metres are needed to achieve a total height of 48 metres.
