What is the volume of the regular pyramid below?

A. 256 units(cube)
B. 768 units
C. 384 units
D. 128 units

Answer 1

First, set up the equation.
V=(l*w*h)/3
Substitute the values for the variables.
V=(8*8*6)/3
Simplify.
V=(384)/3
V=128 cubic units

Answer 2

Answer: The correct options is (D) 128 units³.

Step-by-step explanation: We are given to find the volume of the regular pyramid shown in the figure.

The VOLUME of a regular pyramid with base area 'b' square units and height 'h' units is given by

`V=(1)/(3)* b* h.`

In the given figure, we have

base area = 8 × 8 = 64 units² and height, h = 6 units.

Therefore, the volume of the regular pyramid is

`V=(1)/(3)* b* 64* 6=(1)/(3)* =128~\textup{units}^3.`

Thus, the required volume is 128 units³.

Option (D) is correct.
