Question

Подарок упакован в коробку, которая имеет форму прямоугольного параллелепипеда. Длина двух сторон грани основания —8 см и 12 см, длина бокового ребра коробки- 19 см. Определи необходимую длину ленты для упаковки, если для завязывания банта уйдёт 33 см ленты

Answer 1

Ответ:

2*(8+13)+2*(8+14)=2*(8+13+8+14)=2*43=86 см - длина ленты вокруг коробки

86+34=120 см=1 м 20 см - длина ленты для упаковки

Calculation of Ribbon Length for Gift Wrapping

To determine the necessary length of ribbon for wrapping the gift, we need to calculate the total length of all the edges of the rectangular parallelepiped box and add the length required for tying the bow.

Given information: - Length of one side of the base: 8 cm - Length of the other side of the base: 12 cm - Length of the lateral edge of the box: 19 cm - Length of ribbon required for tying the bow: 33 cm

To calculate the total length of all the edges, we need to consider the dimensions of the box. The box has two sides with lengths of 8 cm and 12 cm, and the lateral edge has a length of 19 cm.

The total length of all the edges can be calculated using the formula:

Total length of edges = 2 * (length of base side 1 + length of base side 2) + 4 * length of lateral edge

Substituting the given values into the formula:

Total length of edges = 2 * (8 cm + 12 cm) + 4 * 19 cm

Simplifying the equation:

Total length of edges = 2 * 20 cm + 76 cm

Total length of edges = 40 cm + 76 cm

Total length of edges = 116 cm

To this, we need to add the length required for tying the bow, which is 33 cm.

Therefore, the necessary length of ribbon for wrapping the gift is:

Total length of ribbon = Total length of edges + Length for tying the bow

Total length of ribbon = 116 cm + 33 cm

Total length of ribbon = 149 cm

So, the necessary length of ribbon for wrapping the gift is 149 cm.
