A Popsicle is a square prism with a base edge length of 3 inches. When the Popsicle is frozen a 7 inch stick is frozen inside as the image shows. After frozen, 1 inch of the stick remains outside the Popsicle. What is the length of AC, to the nearest inch?

    well i mean, logically, i would think it would be one 6 inches, just because of the way it is worded. But i feel like that's probably not what they're asking you to do, rather, i think they want a Pythagorean theorem problem

    so you first have to find the length of a then c

    do you know how to use the Pythagorean theorem?

    so if you plug 3 in for a and b in the first one, you get a=sqrt(18)

    then you use that number and 6 in the next equation to find AC which is 7.35

    I still don't get this sorry I was working on find the area of a rhombus using the Pythagorean theorem but for some reason this doesn't make sense to me .

    How did you get 7.35?

    i used the pytagorean theorem once with 3 and 3 for a and b, and again with sqrt(18) and 6 to get 7.35

    so the answer is 7.35?

    ok so it would be 4.24^2 +6 ^2 =59.9776 so 7.35 is the square root

    yeah that's correct, sorry i wish i could explain it better! just you have to use the Pythagorean theorem twice. Yup thats right!

    But is says round to nearest inch would it be 7.3?

    or does it stay 7.35
