Find the volume of the pyramid shown below.
Correct Answer
1,280 cm³
Explanation
The base is a rectangle 16 cm by 12 cm, so:
\[B = 16 \times 12 = 192 \text{ cm}^2\]
\[V = \frac{1}{3}Bh = \frac{1}{3}(192)(20)\]
Substitute 192 for \(B\) and 20 for \(h\).
\[= \frac{1}{3}(3{,}840) = 1{,}280\]
The volume of the pyramid is 1,280 cm³.
