Question

If the height of a square pyramid is 10 m and its base edge is 12 m long, then find its volume.

• A. $840m^3$
• B. $408m^3$
• C. $480m^3$
• D. $48m^3$

Answer 1

The correct option is C

$480m^3$

Given:
Height of the square pyramid = 10 m
Length of base edge of the square pyramid = 12 m

Volume of square pyramid
$=\frac{1}{3}\times \text{Base area}\times \text{Height}$

$=\frac{1}{3}\times 12\times 12\times 10$

$=4\times 12\times 10=480m^3$
