A solid right pyramid has a square base with an edge length of [tex]\( s \)[/tex] units and a height of [tex]\( h \)[/tex] units.

Which expression represents the volume of the pyramid?

A. [tex]\(\frac{1}{4} s^2 h\)[/tex] units[tex]\(^3\)[/tex]
B. [tex]\(\frac{1}{3} s^2 h\)[/tex] units[tex]\(^3\)[/tex]
C. [tex]\( s^2 h \)[/tex] units[tex]\(^3\)[/tex]
D. [tex]\( 3 s^2 h \)[/tex] units[tex]\(^3\)[/tex]



Answer :

To determine the volume of a solid right pyramid with a square base, we need to follow a few steps:

1. Understand the Volume Formula for a Pyramid:
The general formula for the volume [tex]\( V \)[/tex] of a pyramid is:
[tex]\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]

2. Calculate the Base Area:
Since the pyramid has a square base, the area of the square base can be calculated using the edge length [tex]\( s \)[/tex]. The area [tex]\( A \)[/tex] of a square with edge length [tex]\( s \)[/tex] is:
[tex]\[ A = s^2 \][/tex]

3. Substitute the Base Area and Height into the Volume Formula:
The height of the pyramid is given as [tex]\( h \)[/tex]. Using the formula for the volume of a pyramid, we substitute the base area and height:
[tex]\[ V = \frac{1}{3} \times s^2 \times h \][/tex]

So, the expression that represents the volume of the solid right pyramid with a square base and height [tex]\( h \)[/tex] is:
[tex]\[ \frac{1}{3} s^2 h \][/tex]

Therefore, the correct choice from the given options is:
[tex]\[ \frac{1}{3} s^2 h \text{ units}^3 \][/tex]
