Can You Fit a 46cm Rod in this Box? 📦 3D Pythagoras Theorem Explained!

📐 Can a 46cm metal rod fit inside a rectangular box measuring 20cm x 15cm x 40cm? 📦 In this video, we break down a classic 3D Pythagoras theorem problem step-by-step. You will learn how to first find the face diagonal (x) of the base, and then use that to calculate the ultimate space diagonal (y) connecting the furthest corners of the box. If you are building your Key Stage 3 or Key Stage 4 foundations, this walkthrough is exactly what you need to master spatial geometry and understand how Pythagoras works in the real world! 🔔 Subscribe to Tutor Cletus Okoli (Master Global Mathematics) for more step-by-step math tutorials! #KS4Maths #KS3Maths #MathsFoundations #PythagorasTheorem #LearnMaths
