Question

What is the volume of a pyramid 5 feet tall if its base is a square 4 feet by 4 feet

Answer 1

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

                               = $\frac{5*4*4}{3}$

                               = $\frac{80}{3}$

                               = $26.67 ~ ft^{3}$  ----> rounded to the nearest hundredth 

Answer 2

V = (1/3) * Base Area * height.

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

=  26. 6667 cubic feet.
