Question

can anybody help me on this

Answer 1

Answer: first option

Step-by-step explanation:

The volume of a regular pyramid can be calculated with the following fromula:

$V=\frac{B*h}{3}$

Where B is the area of the base of the pyramid and h iis the height of the pyramid.

The base is a square, therefore, its area B is:

$B=side^2\\B=(2units)^2\\B=4units$

You know that the height is 3, therefore, you can substitute these values into the formula.

THerefore, the volume of the pyramid is:

$V=\frac{4units^2*3units}{3}$

$V=4units^3$

Answer 2

Answer:

4 units³

Step-by-step explanation:

The formula for the volume of a pyramid is

V = (1/3)(base area)(height)

Here the base area is (4 units )² and the height is 3 units.

Thus, the volume of this regular pyramid is

V = (1/3)(4 units²)(3 units)

   =  4 units³
