The height of a pyramid on square base is 15cm. if the volume is 80cm^3, find the area of the square base.
A
8cm2
B
9.6cm2
C
16cm2
D
25cm2
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Volume of pyramid with square base = \(\frac{\text{base area} \times height}{3}\)
\(80 = \frac{\text{base area} \times 15}{3}\)
\(80 = 5 \times \text{base area}\)
\(\text{Base area} = 16 cm^2\)
