Question

The base of the right pyramid is a square of side 16 cm and height 15 cm. Its volume $\left(c{m}^3\right)$ will be

• A. $3840$
• B. $1920$
• C. $1280$
• D. $960$

Answer 1

Answer: (C)

$1280$

Area of the base $=$ $(16\times 16)c{m}^2$
Volume of the pyramid $=$ $\frac{1}{3}\times Bh$
Volume of the pyramid $=$ $\frac{1}{3}(16\times 16)\times 15$
$=1280c{m}^2$
