What is the volume of a pyramid with 12cm height 4cm base and 3 cm length cubed.

The volume of a pyramid is given by the formula:

V = (1/3) * base area * height

First, calculate the area of the base of the pyramid:

A = length * width
A = 4cm * 3cm
A = 12 cm^2

Now, calculate the volume of the pyramid:

V = (1/3) * 12cm^2 * 12cm
V = (1/3) * 144cm^3
V = 48cm^3

Therefore, the volume of the pyramid is 48 cubic centimeters.
