Right, so this time we know the diagonal, length of the diagonal, and we need to find the width.
00:07
So, starting the same thagon theorem as always, in terms of the diagonal squared, length squared plus width squared plus height squared, well, if we want to get the width on its own, we need to solve for w.
00:28
So we pull the length over here and the height over here, and then take the square root of everything except for the width.
00:39
And we can solve the w, and w is the square root of d squared minus l squared minus h squared.
00:54
And we have those numbers in our table.
00:56
So the width squared is equal to, let's see, 65 squared minus 60 squared minus height, sorry, the height was 60, and then minus the length squared, so 24 squared...
