Answer:
V = 1243.5 in³
Step-by-step explanation:
(see attached pic for reference)
The volume of a square pyramid is given as
V = (1/3) b²h,
where,
V = volume of square pyramid (we are asked to find this)
b = base length (given as 18.5 in)
h = height (given as 10.9 in)
Substituting the given values above into the equation:
V = (1/3) b²h
V = (1/3) (18.5)²(10.9)
V = 1243.5083
V = 1243.5 in³ (rounded to nearest tenth)
