Answer :

Given:
height (h) = 5 feet
base length (l) = 4 feet
base width (w) = 4 feet
Now,
Volume of a pyramid = [tex] \frac{l*w*h}{3} [/tex]

                               = [tex] \frac{5*4*4}{3} [/tex]

                               = [tex] \frac{80}{3} [/tex]

                               = [tex]26.67 ~ ft^{3} [/tex]  ----> rounded to the nearest hundredth 
V = (1/3) * Base Area * height.

   =  (1/3) * (4*4) * 5 =  80/3  cubic feet.

=  26. 6667 cubic feet.
