Question

3. Найдите площадь поверхности прямоугольного па- раллелепипеда, если его измерения равны 5 см, 6 см и 8 см. Обесните пж это я нечего не понел у нас завтра кр 5 класс​

Answer 1

Ответ:

236 см^2

Пошаговое объяснение:

S = 2(ab + bc + ac)

S = 2 ( 5×6 + 6×8 + 5×8) = 2 (30 + 48 + 40)

S = 2 × 118

S = 236 см^2

Answer 2

Calculating the Surface Area of a Rectangular Parallelepiped

To find the surface area of a rectangular parallelepiped, we can use the formula: Surface Area = 2(lw + lh + wh)

Where: - l = length - w = width - h = height

Given dimensions: - Length (l) = 5 cm - Width (w) = 6 cm - Height (h) = 8 cm

Calculation

Using the formula, we can calculate the surface area: Surface Area = 2(5*6 + 5*8 + 6*8) Surface Area = 2(30 + 40 + 48) Surface Area = 2(118) Surface Area = 236 cm^2

So, the surface area of the rectangular parallelepiped is 236 square centimeters.

This calculation is based on the formula for the surface area of a rectangular parallelepiped, as provided by mathematical principles.
