Please help me geometry

Answer:
B
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] area of base × height, hence
V= [tex]\frac{1}{3}[/tex] × 64 × 8 ≈ 170.7 ( to 1 dec. place )
For this case we have that by definition, the volume of a pyramid is given by:
[tex]V = \frac {1} {3} * A_ {b} * h[/tex]
Where:
[tex]A_ {b}:[/tex] It is the area of the base
h: It's the height
According to the data we have:
[tex]A_ {b} = 64mm ^ 2\\h = 8mm[/tex]
Substituting:
[tex]V = \frac {1} {3} * 64 * 8\\V = \frac {512} {3}\\V = 170.666666667[/tex]
If we round up we have that the volume is[tex]170.7 \ mm ^ 3[/tex]
