Question

What is the volume of the pyramid 7x7x8

Answer 1

you do length x width x be aight divided by 3 to get 392/3

Answer 2

The volume of the pyramid is
`130(2)/(3)\ units^(3)`

Explanation:

we know that

The volume of the pyramid is equal to

`V=(1)/(3)BH`

where

B is the area of the base

H is the height of the pyramid

Find the area of the base B

In this problem we have a square base

`B=7^(2) =49\ units^(2)`

we have

`H=8\ units`

substitute

`V=(1)/(3)(49)(8)=(392)/(3)\ units^(3)`

Convert to mixed number

`(392)/(3)=(390)/(3)+(2)/(3)=130(2)/(3)\ units^(3)`
