4+4+4+4=16 ( б) коробок 

Answer 2

Number of Sides and Bases of the Box

The given drawing depicts an open rectangular box. To determine the number of sides and bases of the box, we need to consider its structure.

A rectangular box has 6 faces, with each face being a rectangle. The box has 3 pairs of parallel faces. The pairs of parallel faces are opposite to each other, and each pair consists of two identical rectangles.

Therefore, the box has 4 lateral faces (also known as the side faces or the vertical faces) and 2 bases (also known as the top and bottom faces).

Equality of Lateral Faces

The question asks which lateral faces are equal to each other. Since the box is a rectangular box, all the lateral faces are equal in size and shape. This means that any two lateral faces of the box are identical to each other.

Area of Paper Required

To calculate the area of paper required to cover the outside of the lateral walls and the bottom of the box, we need to find the total surface area of these parts.

The total surface area of the lateral walls and the bottom of the box can be calculated by finding the sum of the areas of each face. Since the box has 4 lateral faces and 1 bottom face, we need to calculate the area of each face and then add them together.

The area of a rectangle can be calculated by multiplying its length by its width. In this case, the dimensions of the box are given in centimeters. Let's assume the length of the box is L cm, the width is W cm, and the height is H cm.

The area of each lateral face is L x H, and the area of the bottom face is L x W. Therefore, the total surface area of the lateral walls and the bottom of the box is:

Total Surface Area = 4 x (L x H) + (L x W)

Please provide the dimensions of the box (length, width, and height) in centimeters, and I can calculate the total surface area for you.
