Answer:
4*2*5/2=20
Step-by-step explanation:
Answer: If this is a triangular prism we need one more number in order to find the correct answer so if you want to find it easily the formula is for the volume V = 0.5 X b X a X h.
137 in.^2
A = nsa/2
where
n = number of sides = 9
s = length of side = 4.7 in.
a = length of apothem = 6.5 in.
A = (9)(4.7 in.)(6.5 in.)/2
A = 137.475 in.^2
Answer: 137 in.^2
