Question

Решить срочно даю 30б !!!!!!! сторона одного куба 9 сантиметров, а другого 5сантиметров.сколько объем первого куба больше объема второго?во сколько площадь поверхности первого куба больше площади поверхности второго?

Answer 1

9*9*9 = 729 - объем первого
5*5*5 = 125 - объем второго
729-125 = 604- на столько см кубических больше

площадь пов-ти первого
9*9*6 = 486

площадь пов-ти второго
5*5*6 = 150

на сколько больше
486 - 150 = 336

Answer 2

Calculation of the Volume Difference:

To find the volume difference between two cubes, we need to calculate the volume of each cube and then subtract the volume of the smaller cube from the volume of the larger cube.

The formula to calculate the volume of a cube is given by:

Volume of a Cube = (Side Length)^3

Let's calculate the volume of the first cube with a side length of 9 centimeters:

Volume of the First Cube = (9 cm)^3 = 729 cm^3.

Now, let's calculate the volume of the second cube with a side length of 5 centimeters:

Volume of the Second Cube = (5 cm)^3 = 125 cm^3.

To find the volume difference, we subtract the volume of the second cube from the volume of the first cube:

Volume Difference = Volume of the First Cube - Volume of the Second Cube = 729 cm^3 - 125 cm^3 = 604 cm^3.

Therefore, the volume of the first cube is 604 cm^3 greater than the volume of the second cube.

Calculation of the Surface Area Difference:

To find the surface area difference between two cubes, we need to calculate the surface area of each cube and then subtract the surface area of the smaller cube from the surface area of the larger cube.

The formula to calculate the surface area of a cube is given by:

Surface Area of a Cube = 6 * (Side Length)^2

Let's calculate the surface area of the first cube with a side length of 9 centimeters:

Surface Area of the First Cube = 6 * (9 cm)^2 = 6 * 81 cm^2 = 486 cm^2.

Now, let's calculate the surface area of the second cube with a side length of 5 centimeters:

Surface Area of the Second Cube = 6 * (5 cm)^2 = 6 * 25 cm^2 = 150 cm^2.

To find the surface area difference, we subtract the surface area of the second cube from the surface area of the first cube:

Surface Area Difference = Surface Area of the First Cube - Surface Area of the Second Cube = 486 cm^2 - 150 cm^2 = 336 cm^2.

Therefore, the surface area of the first cube is 336 cm^2 greater than the surface area of the second cube.

In summary: - The volume of the first cube is 604 cm^3 greater than the volume of the second cube. - The surface area of the first cube is 336 cm^2 greater than the surface area of the second cube.
