Question

What is the volume, in cubic units, of a pyramid of height 8 and a square base of length 15?

Answer 1

900 cuboc unit

Explanation:

Volume of pryamid= 1/3× area× height

= 1÷3×15^15×8

= 900cubic unit

Answer 2

For this case we have by definition, that the area of a square base pyramid is given by:

`V = \frac {L ^ 2 * h} {3}`

Where:

L: It's the side of the square base

h: It's the height of the pyramid

We have that
`L = 15 \ units`, then
`L ^ 2 = 15 ^ 2 = 225 \ units ^ 2`

Substituting:

`V = \frac {225 * 8} {3}\\V = 600 \ units ^ 3`

Finally, the volume of the pyramid is
`600 \ units ^ 3`

Answer:

`600 \ units ^ 3`
