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)

The sum of four consecutive integers is at least 18. What's the smallest consecutive integer to make this statement true?

Ghella [55]

Let the four consecutive integers be

x , x+1, x+2, x+3

ATQ, Their sum is 18

$\sf \: x + x + 1 + x + 2 + x + 3 = 18$

$\sf \: 4x + 1 + 2 + 3 = 18$

$\sf4x + 6 = 18$

$\sf4x = 18 - 6$

$\sf4x = 12$

$\boxed{ \mathfrak{x = 3}}$

1st number = x = 3
2nd number = x+1 = 3+1 = 4
3rd number = x+2 = 3+2 = 5
4th number = x+3 = 3+3 = 6

The four numbers are 3,4,5,6 respectively and the smallest number among them is 3...~
