Question

What is the volume of a regular pyramid below?

Answer 1

Answer:

3388 units^3.

Step-by-step explanation:

The volume of a pyramid = 1/3 * area of the base * altitude.

So here we have Volume = 1/3 * 84 * 11^2

= 3388.

Answer 2

Answer: B. 3388 units³

Step-by-step explanation:

To find the area of a pyramid, we use the formular;

v = 1/3 Ah

A == area of the base

h = height

h = 84 (from the diagram provided)

we need to calculate the area

area = l × b

=11 × 11

=121

v = 1/3 Ah

= 1/3 × 121 × 84

=10164/3

= 3388

Therefore the volume of the pyramid is 3388 units³
