What is the volume of the regular pyramid below? 84, 11, 11 a. 270 units3 b. 3388 units3 c. 10,164 units3 d. 924 units3

volume of regular pyramid = 3388 units³

Explanation:
Volume of regular pyramid can be calculated using the following rule:
volume of regular pyramid =  * area of base * height
volume of regular pyramid = * length * width * height

Based on the comment you added above, we have:
length = 11 units
width = 11 units
height = 84 units

Substitute with the givens in the above equation to get the volume as follows:
volume = * 11 * 11 * 84
volume = 3388 units³

Hope this helps :)
