The height of a pyramid on square base is 15cm. if the volume is 80cm^3, find the area of the square base.
8cm2
9.6cm2
16cm2
25cm2
स्पष्टीकरण
Volume of pyramid with square base = \(\frac{\text{base area} \times height}{3}\)
\(80 = \frac{\text{base area} \times 15}{3}\)
\(80 = 5 \times \text{base area}\)
\(\text{Base area} = 16 cm^2\)
