A square pyramid has a base side of 6 cm and height 9 cm. Find the volume.

  1. 118 cm³

  2. 108 cm³

  3. 208 cm³

  4. None

Answer: B

Solution

Solution: Volume of a square pyramid \(V=\frac13\times\text{base area}\times h\). Base area \(=6^2=36\text{ cm}^2\). Hence, \(V=\frac13\times36\times9=108\text{ cm}^3\). Trick: Find the square base area first, multiply by height, and divide by 3.
