The volume of a pyramid can be calculated using the formula:
Volume = (1/3) * base area * height
The base area of a rectangle can be calculated by multiplying the length and width:
Base area = length * width
Substituting the given values, we get:
Base area = 8 inches * 12 inches = 96 square inches
Now we can calculate the volume using the formula:
Volume = (1/3) * 96 square inches * 20 inches = 640 cubic inches
Therefore, the volume of Cecilia's model pyramid is 640 cubic inches.
