a rectangular box with dimensions 2 ft by 3 ft by 5 ft is braced internally along a diagonal from the upper left corner to the lower right corner of the box. what is the approximate length of the diagonal brace to the nearest inch?
Answer provided by our tutors
Let 'd' represent the length of the diagonal brace to the nearest inch, d>0.
1 ft = 12 in
Using the Pythagorean Theorem we can write:
d^2 = ((2*12)^2 + (3*12)^2 + (5*12)^2)
