Question

A chessboard is made of 64 small squares. A single square on a chessboard has an area of 7 cm2. How long is the side of the entire board, rounded to the nearest tenth of a centimeter?

Answer 1

if the area of a single square is \(7\) then the side of the single square is \(\sqrt{7}\)
multiply by the number of squares per side

Answer 2

I got 4096..

Answer 3

what did you multiply \(\sqrt{7}\) by ?

Answer 4

I multiplied eight 8 times

Answer 5

ok right, the answer is \(8\times \sqrt7\) but that is certainly not that big number you got

Answer 6

So its 21.2 cm.?

Answer 7

to the nearest tenth, yes

Answer 8

Thank you.
