Question

A spider walks on the outside of a box from point A to B to C to D

Answer 1

The path consists of 4 line segments. Each line segment is the hypotenuse of a different right triangle.

length of line segment AB = $\sqrt{2^{2}+5^{2} } =\sqrt{29} =5.39cm$

length of line segment BC = $\sqrt{3^{2}+4^{2} } =\sqrt{25} =5cm$

length of line segment CD = $\sqrt{3^{2}+5^{2} } =\sqrt{34} =5.83cm$

length of line segment DE $=\sqrt{2.5^{2}+3^{2} } } =\sqrt{15.25} =3.91cm$

The total length of the spider's path is about 20.13 cm.
