What is the volume of this equation?
Pachacha [2.7K]

Answer:

Volume ≈ 33.33 cubic feet

Step-by-step explanation:

The question is:

<em>Find the volume of a right square pyramid with base square edges measuring 5 feet each and a height of the pyramid be 4 feet.</em>

<em />

So, the base is a square with side length 5 feet.

And the height of the pyramid is 4 feet.

The volume of a pyramid is given by the formula:

V=\frac{a^2 h}{3}

Where

a is the square base side length (given as 5)

h is the height of the pyramid (given as 4)

Now we substitute and find the value:

V=\frac{a^2 h}{3}\\V=\frac{(5)^2 (4)}{3}\\V=33.33

The volume is around 33.33 cubic feet
