The length of the base of the pyramid is 9 inches
<em><u>Solution:</u></em>
<em><u>The volume of pyramid is given by formula:</u></em>
Where, "l" is the length and "w" is the width and "h" is the height
Given that,
volume of pyramid = 81 cubic inches
Also given that, l equals w equals 3 h
<h3>l = w = 3h </h3>Substitute the values in formula,
Thus height = 3 inches
We have to find the length
l = 3h
l = 3(3) = 9
Thus length of the base of the pyramid is 9 inches
