Answer:
The volume is 191.3
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by the formula:
where B is the area of the pyramid's base, and H its height. So, in our case, the base is a square of length 7.5 cm, which gives 56.25 cm^2
Now, we use this value and the height 10.2 cm to find the volume:
