How many bricks, each sized 25 cm by 15 cm by 8 cm, are needed to build a wall measuring 10 m in length, 4 m in height, and 5 m in thickness, if 10% of the wall's volume is taken up by mortar?

Explanation

First, calculate the total volume of the wall in cubic centimeters, then reduce it by 10% to account for mortar. Next, find the volume of a single brick and divide the adjusted wall volume by the brick volume to determine the number of bricks required.
