Question

площадь поверхности куба 180. Найти площадь одной грани куба.

Answer 1

 

чтобы найти площадь одной грани,нужно площадь поверхности куба разделить на 6

Значит площадь одной грани=30.

Answer 2

Площадь полной поверхности равна 6 площадям одной грани (у куба 6 граней, равных между собой)

1) 180:6=30 - площадь одной грани куба

ответ: 30

Answer 3

Finding the Surface Area of a Cube

To find the surface area of a cube, we need to know the total surface area and then divide it by the number of faces. In this case, we are given that the total surface area of the cube is 180.

Let's calculate the surface area of one face of the cube.

Step 1: Find the total surface area of the cube. The total surface area of a cube is given by the formula: 6 * (side length)^2.

Step 2: Divide the total surface area by the number of faces. Since a cube has 6 faces, we divide the total surface area by 6 to find the surface area of one face.

Let's calculate the surface area of one face using the given information.

Step 1: Find the side length of the cube. To find the side length, we need to take the square root of the total surface area divided by 6.

Let's calculate the side length of the cube.

180 / 6 = 30

The side length of the cube is 30.

Step 2: Calculate the surface area of one face. The surface area of one face is given by the formula: (side length)^2.

Let's calculate the surface area of one face.

(30)^2 = 900

Therefore, the surface area of one face of the cube is 900 square units.
