Answer:
Thus, volume of pyramid = cm³
Step-by-step explanation:
Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.
We have to choose from the given options an expression for the volume of the pyramid.
Volume of pyramid =
Since base is a square with edge length x cm.
Area of square = (side)² = x²
Thus, volume of pyramid = cm³
