Homework Level 3-4 Lesson 9 - Geometry

Pdf Summary

The document is a geometry homework assignment for Math Kangaroo Class Level 3-4, consisting of five questions. It includes visual questions that require students to either calculate or visualize geometric shapes and their properties.<br /><br />1. **Rectangles Counting**: The first question asks how many rectangles are present in a given diagram. The answer provided is 12 rectangles.<br /><br />2. **Piece of Paper**: The second problem involves identifying the shape of the other piece when a square paper is cut into two. The piece may be rotated but not flipped. The correct option from those given is E.<br /><br />3. **Right Side View**: The third question requires students to visualize what a certain figure looks like from its right side. The correct view is option B.<br /><br />4. **Perimeter of Smallest Square**: The fourth question concerns calculating the perimeter of one of the smallest squares in a structure consisting of six squares. The largest square has a perimeter of 280 cm. The answer given for the perimeter of one of the smallest squares is 40 cm.<br /><br />5. **Painting a Cube**: The final question involves a 3x3 cube made from 27 smaller cubes. Eight corner cubes are removed, and the remaining structure is painted. Students need to determine how many faces are painted. The answer is 54 faces.<br /><br />Each question requires students to use spatial reasoning and basic mathematical calculations to find the correct answer. Solutions to the exercises are provided at the end of the document.
