To find the volume of a rectangular pyramid, you need to use the formula:
V = (1/3) * base area * height
First, calculate the area of the base:
Area = length * width
Area = 9 cm * 4 cm
Area = 36 cm^2
Now, substitute the values into the formula:
V = (1/3) * 36 cm^2 * 21 cm
V = (1/3) * 756 cm^3
V = 252 cm^3
Therefore, the volume of the piece of cheese is approximately 252 cm^3.
The closest option is:
D. 266.7
