The information provided is:
<em>a</em> = side of square = 4 cm
<em>h</em> = 3 cm
Compute the area of the square base as follows:

Compute the volume of squared-base pyramid as follows:


Thus, the volume of the pyramid is 16 cm³.
Answer:
39
Step-by-step explanation:
d = s - 15

2s -15 = 63
2s = 78
s = 39
