The volume of a pyramid is \(\displaystyle{V}={\frac{{{1}}}{{{3}}}}{B}{h}\) where B is the area of the base and hh is the height of the pyramid.

From the figure, the base of the pyramid is a rectangle with a length of l=2 ft and a width of w=1 ft. The area of the base is then B=lw=2(1)=2.

From the figure, the height of the pyramid is h=2 ft. The volume is then \(\displaystyle{V}={\frac{{{1}}}{{{3}}}}{B}{h}={\frac{{{1}}}{{{3}}}}{\left({2}\right)}{\left({2}\right)}={\frac{{{4}}}{{{3}}}}={1}{\frac{{{1}}}{{{3}}}}{f}{t}^{{{3}}}\)
