Question

(Pythagorean theorem)

The box above is 15 centimeters long, 4 centimeters wide, and 3 centimeters tall. What is the length of the diagonal S of the bottom side?

Answer 1

Is there an image of this or something? I’m not sure where S is supposed to be. Is S on the bottom of the box?

Pythagoras theorem is: a^2+b^2=c^2

If it is the bottom of the box you need, then:

a=15, b=4, c=x

15^2+4^2 = 241

c^2 = 241

c = √241

Which can either be written like that or is 15.5241747
Or
15.52 (2 d.p.)

Let me know if that’s the side it meant?
