God I remember when I had to that last year in 7th grade honors. I know you have to set up a proportion.
25/6. X/4. Find x and you get your answer
&4 - $2= $2 You have to round the numbers to the closest one right.
What is the fourth persons time and, with these numbers it should be anything lower than 9.75.
The answer is 32, depending on how you do the math will be different outcomes
Answer:
Volume = ⅓n²(n-1) or ⅓(n³ - n²)
Step-by-step explanation:
Given
Solid Shape: Right pyramid
Edge= n units
Height= n - 1 units
Required
Volume of the pyramid
The volume of a right pyramid is
Volume = ⅓Ah
Where A represents the area of the base
h represent the height of the pyramid
Since it has a square base;
The area is calculated as follows
Area, A = edge * edge
A = n * n
A = n²
Recall that
Volume = ⅓Ah
Substitute n² for A and n - 1 for h
The expression becomes
Volume = ⅓ * n² * (n - 1)
Volume = ⅓n²(n-1)
The expression can be solved further by opening the bracket
Volume = ⅓(n³ - n²)
