A rectangular pyramid measures three feet by four feet at the base and has a height of seven feet. find its volume.

Slav-nsk [51]

The volume of the rectangular pyramid is 28 cubic feet.

<h3>How to find the volume of the pyramid?</h3>

The volume of a pyramid of base B and height H is given by:

$V = (1/3)*B*H$

Here we know that the height is H = 7ft, and the base is a rectangle of 4ft by 3ft, so the area of the base is:

$B = 4ft*3t = 12ft^2$

Then the volume of the pyramid is:

$V = (1/3)*7ft*12ft^2 = 28ft^3$
