Question

Given the rectangular solid. Given RS = 6, ST = 3, and SL = 4, find the required measure.

KT = ?
(Hint. There's a 6 in the answer.)

Answer 1

Task steps: Find the length of RT (Pythagoean theorem). Note that KRT is a right triangle. KR and RT known, find KT (another Pythagorean theorem problem).

Answer 2

SL = KR = 4 = z = height
ST = QR = 3 = y = length

You're then using the Pythagorean Theorem for 3D which the theorem applied TWICE.
