Question

Объём куба 125 кв.сантиметров.Вычеслите реброи площадь поверхности куба.

Answer 1

Обьем куба равен

$V=a^3;$

Ребро куба равно

$a=\sqrt[3] V;$

Площадь полной поверхности куба равна

$S=6a^2;$

 

1)$a=\sqrt[3] 125=5$ - см равно ребро куба

2) 6*5*5=150 кв.см - площадь полной поверхности куба

ответ: 150 кв.см

Answer 2

тк  это куб то V=abc, а авс- это измерения то они равны: а=5( т к 5"3=125) , значит ребро равно 5, площадь поверхности= Sбок+ 2Sосн, Sбок= Росн* h= 20*5=100, Sосн= 25, площадь поверхности= 100+50= 150

ответ:150

Answer 3

Calculation of the Cube's Edge and Surface Area

To calculate the edge and surface area of a cube with a volume of 125 cubic centimeters, we can use the formula and information provided.

1. Calculation of the Cube's Edge: The volume of a cube is given by the formula V = a^3, where V is the volume and a is the length of one edge of the cube. In this case, the volume is given as 125 cubic centimeters.

To find the length of one edge, we need to solve the equation a^3 = 125. Taking the cube root of both sides, we find that a = 5.

Therefore, the length of one edge of the cube is 5 centimeters.

2. Calculation of the Cube's Surface Area: The surface area of a cube is given by the formula A = 6a^2, where A is the surface area and a is the length of one edge of the cube.

Substituting the value of a as 5, we can calculate the surface area as follows: A = 6 * 5^2 = 6 * 25 = 150 square centimeters.

Therefore, the surface area of the cube is 150 square centimeters.

In summary: - The length of one edge of the cube is 5 centimeters. - The surface area of the cube is 150 square centimeters.
