Gifts must be anyone’s favourite things! So basically our favourite things come in Boxes. We can make boxes of the desired size and shape by joining squares and rectangles of corresponding sizes. In this chapter, we will learn about the relationship between 2D and 3D objects and how to visualise their shapes.

**FAQs on Boxes and Sketches**

**Question 1: What is the box method in math?**

**Answer:** It is a strategy for multiplying large numbers. Moreover, it is an alternative to the standard algorithm of multiplication. In addition, the box method is based on the area array representation of multiplication. And it is proportional to the size of the numbers being multiplied.

**Question 2: How to calculate the area of a box?**

**Answer:** All boxes have different height, width, and length and if all these lengths are the same then these boxes will become a perfect square. However, the volume of each boxes inside is H × W× L. Besides, the outer surface area of a box is 2(H × W) + 2(H × L) + 2(W × L).

**Question 3: How many sides does a box have?**

**Answer:** Boxes generally come in sizes that are similar to a square or rectangle. And every box has six sides that include the top and bottom, front and back, and left side and right side.

**Question 4: What is a math box?**

**Answer:** It is sole, multi-leveled resources that provide activities designed to improve the mathematical skills, strategies, knowledge and reasoning and problem-solving abilities of students. In addition, math boxes are large comprehensive resources that provide meaningful and coherent mathematics practices.
