Question

Найдите площадь поверхности прямоугольного параллелепипеда длиной 5 м, шириной 4 м, выстой 3 м.

Answer 1

Это легко. Ведь площадь это длина×ширина

Answer 2

Calculation of Surface Area of a Rectangular Prism

To find the surface area of a rectangular prism, we need to calculate the area of each face and then sum them up.

Given the dimensions of the rectangular prism: - Length = 5 m - Width = 4 m - Height = 3 m

We can calculate the surface area using the formula:

Surface Area = 2lw + 2lh + 2wh

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

Substituting the given values into the formula, we get:

Surface Area = 2(5)(4) + 2(5)(3) + 2(4)(3)

Simplifying the equation, we have:

Surface Area = 40 + 30 + 24

Calculating further, we find:

Surface Area = 94 square meters

Therefore, the surface area of the rectangular prism is 94 square meters.
