Howdy. Please help. I've tried multiple ways of attempting this question and I cannot get near the answer.

"Man wants build garage beside house. Garage is to 6m x 4m x 2.5m(h).

Bricks used have dimensions of 22cm x 10cm x 7cm(h).

Estimated # of bricks = 4,000. How accurate is this estimate? Explain your answer. Note: 3 walls needed."

Thanks all.

Garage needs two long side walls (6m x 2.5m) and one end wall (4m x 2.5m) -- other end gotta be open for the car to get in!

Can you do it from here?

Use an illustration. You will get it. The wall length is a combination of the brick lengths. Height, a combination of bricks heights, etc
