The given figure is a square base pyramid. The formula for determining the volume of a square base pyramid is expressed as
Volume = 1/3 x base area x height
From the diagram,
height = 1
base area = 1 x 1 = 1
Volume = 1/3 x 1 x 1
Volume = 0.333
Rounding to the nearest hundredth, volume of pyramid = 0.33 cubic yard
