Help with this? I can't solve it

[Laurenkiernan0507]

Can anyone help with this question? I've done all the working out as per the revision but still end up with the wrong answer and it's frustrating me.

I'd also love to see the working out to get the answer so I understand how to do it?

Sum up the lengths of the yard that will get walled. I get 25.2m.

Divide the wall length by the the length of the bricks. Remember bricks are given in mm, the wall length in m.
Divide the wall height by the brick height.

Multiply these two numbers.

I get 672 bricks.

Is this part of the other question you posted? There's no mention of wall depth in this question. The other question mentions a wall depth.

If there is depth to the wall divide that depth by the width of the bricks and multiply that times the 672 bricks found w/o any wall depth.

Thank you! I managed to get it right just after posting this, using similar workings to yours. I don't know why but it seemed so simply once I figured out the workings, I think I was over thinking it massively. Its my last module out of 15, I'm so over it! ??
