Set B- Level 1-2 - 3D Visualization - Homework

Pdf Summary

This document is a homework assignment for a 3D visualization class at the Math Kangaroo competition, specifically designed for levels 1-2. The assignment includes several questions related to problems involving counting cubes and understanding spatial structures, as well as visualizing arrangements.<br /><br />1. The first question asks how many blocks were used to build a particular figure, with the answer provided being 10.<br /><br />2. The second question inquires about the number of cubes that share a face with exactly three other cubes, with the answer given as 4.<br /><br />3. The third problem involves a scenario where Joyce has glued together 12 cubes and painted the exterior. The question asks how many surface squares were painted, and the answer is stated to be 46.<br /><br />4. The fourth question involves visualizing and comparing buildings constructed by Paul and Jon using cube blocks. Participants are instructed to create a top view picture of Jon’s building similar to the provided ones for Paul’s. Specific instructions or an answer aren't provided here.<br /><br />5. The final exercise involves arranging numbers 1 through 6 on the faces of a standard die so that opposite faces add up to the same sum, with pairs given as: 1 and 6, 2 and 5, 3 and 4.<br /><br />In summary, the tasks aim to develop spatial thinking and visualization skills by using cube arrangements and dice, with given solutions for some questions to aid understanding.
