Question

What is the volume of a rectangular pyramid with a 10" base and an 8" base and a 12" height?

Answer 1

320in^3

Explanation:

V=lwh/3

V=(10)(8)(12)/3

V=960/3

V=320

Answer 2

For this case we have by definition, that the volume of a rectangular pyramid is given by:

`V = \frac {a * b * h} {3}`

Where:

a, b: Are the sides of the rectangular base

h: It's the height of the pyramid

Substituting the values:

`V = \frac {10 * 8 * 12} {3}\\V = \frac {960} {3}\\V = 320`

Thus, the volume of the pyramid is 320 cubic inches

Answer:

`320 \ in ^ 3`
