If you have rectangular box with length = 40 cm, width = 30 cm, and height = 70 cm; what is the largest length stick that could fit inside the box (rounded to the nearest cm) A) 80 cm B) 86 cm C) 90 cm D) 96 cm
Accepted Solution
A:
Call the box A'B'C'D'.ABCD We have AC' as the longest possible length of the stick. AC'^2 = A'C'^2 + C'C^2 = (40^2 + 30^2) + 70^2 = 7400 => B as 86 x 86 = 7368
