Answer:
V = 83.0 cm^3
Step-by-step explanation:
To find the volume of the squared pyramid you use the following formula:
[tex]V=\frac{1}{3}Bh[/tex] ( 1 )
B: base of the pyramid = 19.6 cm^2
h: height of the pyramid = 12.7 cm
you replace the values of B and h in the equation ( 1 ):
[tex]V=\frac{1}{3}Bh=\frac{1}{3}(19.6cm^2)(12.7cm)\\\\V=82.97cm^3\approx 83.0cm^3[/tex]
hence, the volume of the pyramid is 83.0 cm^3
