Step-by-step explanation:
Let
P------> the perimeter of a regular polygon
a-----> the apothen
A-----> the area of a regular polygon
we know that
The formula to calculate the area of a regular polygon is equal to
A=\frac{1}{2}PaA=

Answer:
The length of the edge of the container is 5 centimeters
Step-by-step explanation:
The volume of a cube is V = L³, where L is the length of its side
∵ The side of the small cube is 1 centimeter
→ By using the rule above
∴ The volume of the small cube = (1)³ = 1 cm³
∵ Mario uses 125 small cubes to make the container in the shape of a cube
→ Multiply the number of the small cubes by the volume of each cube to
get the volume of the container
∴ The volume of the container = 125 × 1 = 125 cm³
→ Use the rule of the volume above to find the length of the side
of the container
∵ V = 125 cm³
∴ 125 = L³
→ Take cube root to both sides to find L
∵
= ![\sqrt[3]{L}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BL%7D)
∴ 5 = L
∴ The length of the edge of the container is 5 centimeters
Answer:
Alice had £18 and Alice had £4
1.75 km = 1750 m
1750 m - 800 m = 950 m
950 m + 910 m = 1860 m
1917 m - 1860 m = 57 m
Answer: 57 more meters
