Question

Normal capacity holds 140k the wall has to hold 150% of the normal capacity,the retaining wall has to hold about 70k litres more incase of a breach?​

Answer 1

To find the required capacity for the retaining wall, calculate 150% of the normal capacity of 140,000 liters and add an additional 70,000 liters, totaling 280,000 liters.

Step-by-step explanation:

The question asks us to calculate the capacity a retaining wall must hold when it is required to contain 150% of its normal capacity, plus an additional 70,000 liters in case of a breach. If the normal capacity is 140,000 liters, then 150% of this amount is 210,000 liters (1.5 × 140,000 liters). To meet the breach condition, we need to add an extra 70,000 liters. Therefore, the total capacity the wall must be able to hold is 210,000 liters + 70,000 liters, which equals 280,000 liters in total.
