Geometry

The formula for the area of a sector is

k =  \frac{m}{360} \times a

Input the things which you already know. (m)

k =  \frac{45}{360}  \times a

a=πr^2

a=36π

Input this into the equation.

k =  \frac{45}{360}  \times 36 \times 3.14

k =  \frac{45}{360}  \times 113.04

k = 14.13

Damm [24]

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes
