what is the answer of this problem?

$${\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{12}}{\mathtt{\,\times\,}}{\mathtt{36}} = {\mathtt{6\,480}}$$

6480 square inches

45 sq ft

(I hope you don't mind that I'm not doing the lengthy solution)

Well....let's start with number of patches per person* area each patch covers

Each patch covers 6 sq inches and there will be 12 per person so 6*12=72

Now we do, solution of first problem * number of members

15 members and the solution was 72

Just to break the problem down further,  I will do (10*72)+(5*72)

10*72=720

Since 5 is half of ten, but the second number is the same, then the answer of 5*72=360

720+360=1080

1080 is the answer in square inches

7.5 square feet is the answer you want

6 square inches on a side = 36 sq in

So, the number of square inches is given by

15 * 12 * 36 = 6480 sq in

And to convert this to square feet, we have

6480 sq in x [ 1 square ft / 144 sq in ] = 45 sq ft.

Beat you CPhill....LOL

I get nothing out of the deal????

Remember, happy7, 6 inches on a side = 36 sq in......but I gave you points for a good effort......

Oopsies!  Misread!

thank you
