Pythagorean theorem in 3 dimensions: sqrt(115^2 + 90^2 + 80^2) = 166.5

Label (length,width,height,diagonal length) = (l,w,h,d);

Then d^2 = l^2 +w^2+h^2 = (115^2+90^2+80^2)mm^2 = 100(11.5^2 +145)mm^2

= 100(121+11.25+145)mm^2 = 100(277.25)mm^2 = (166.5082581 mm)^2 =;

167 mm rounded to nearest mm.
