weird can see it... sigh nether mind let me write it out:
The pond is in the shape of a rectangle with length 7m and width 4m
The path is 3m wide
Ali is going to cover the path with gravel
One bag of gravel will cover 10cm3 of the path
How many bags does Ali need to buy?

Thanks just really tired and cannot think rip

Does the path go all the way around the lake?

Also why have you got 10cm3 when there is no volume needed?

Ok, well start by working out how long the path needs to be around the lake, using the measurements of 7m and 4m to help you. Then you know how long the paths needs to be. Then you can use this and the width of your path to work out the full area of the path.

I'm not going to tell u the answer straight away but say the area of the path is A.
Then you can work out how many 10cm2 bags of gravel you need to make up at the number A.
