Question

Коробка имеет форму прямоугольного параллепипида (без крышки). Известно, что лбъем коробки равен 30 см кубических, а стороны ее основания - 3 см и 5 см. Сколько бумаги потребуется для оклейки коробки изнутри?

Answer 1

Все тоже самое только вместо 18 поставь 30 вместо  3 поставь 6 и в место 5 поставь 10
Потребуется Sбок+Sосн;h=180/(6*10)=3 см;Sбок=2*(6*3)+2*(10*3)+(6*10)=36+60+60=156 см² - тебе потребуется.

Answer 2

Calculation of Paper Required for the Inside of the Box

To calculate the amount of paper required to cover the inside of the box, we need to find the surface area of the box's inner walls.

The box is in the shape of a rectangular parallelepiped, with dimensions of 3 cm by 5 cm for the base and a volume of 30 cubic cm.

To find the surface area of the inner walls, we can use the formula for the surface area of a rectangular parallelepiped, which is given by:

Surface Area = 2lw + 2lh + 2wh

Where: - l is the length of the box - w is the width of the box - h is the height of the box

In this case, the length (l) and width (w) of the box are 3 cm and 5 cm, respectively. The height (h) can be calculated by dividing the volume of the box by the product of the length and width:

h = Volume / (l * w)

Substituting the given values, we have:

h = 30 cm^3 / (3 cm * 5 cm)

Now we can calculate the height (h) and substitute it into the surface area formula to find the total surface area of the inner walls.

Let's do the calculations:

h = 30 cm^3 / (3 cm * 5 cm) = 2 cm

Surface Area = 2lw + 2lh + 2wh = 2(3 cm * 5 cm) + 2(3 cm * 2 cm) + 2(5 cm * 2 cm) = 30 cm^2 + 12 cm^2 + 20 cm^2 = 62 cm^2

Therefore, the total surface area of the inner walls of the box is 62 square centimeters.

To cover the inside of the box, you will need 62 square centimeters of paper.

Please note that the calculations provided are based on the given dimensions and volume of the box.
