CBSE Class 5 Mathematics Boxes And Sketches Worksheet Set 01

Competency : Understanding Basic Concepts

Question 1. Which of these nets will make a cube, tick them
Answer: A cube has 6 square faces. When examining the three given nets from left to right:
1. The first net has only 5 squares (3 in the top row and 2 below), so it does not fold into a closed cube.

2. The second net shows 6 squares arranged in a cross shape, which is a standard net of a cube.
3. The third net is a staircase of 5 squares, which is not a cube net because a cube needs 6 squares.

Therefore, only the second net (the cross shape) will make a cube when folded.

In simple words: Only the cross-shaped net with 6 squares can be folded into a closed cube box.

Exam Tip: Always remember that a cube net must consist of exactly 6 squares and cannot have any overlapping or disconnected faces when folded.

Question II. Match each net provided in column A to its corresponding object in column B
Answer:
1. Net 1 (Cone net showing a sector and a circle) matches with Object in B: Cone (Item 2 in column B)
2. Net 2 (Cross net of 6 squares) matches with Object in B: Cube (Item 3 in column B)
3. Net 3 (Rectangle formed by rolling a sheet with two circular ends) matches with Object in B: Cylinder (Item 1 in column B)
In simple words: Match the flat 2D pattern to the 3D solid shape it forms when folded or rolled.

Exam Tip: Visualize the unfolding of everyday 3D objects like soup cans (cylinders) or dice (cubes) to easily identify their 2D nets.
