Question

what is the volume of this rectangular pyramid? 11 mm 12 mm 18 mm cubic millimeters submit

Explanation:

Step1: Recall pyramid volume formula

The volume $V$ of a rectangular pyramid is $V = \frac{1}{3} \times \text{base area} \times \text{height}$

Step2: Calculate base area

The base is a rectangle with length $18$ mm and width $12$ mm.
$\text{Base Area} = 18 \times 12 = 216$ $\text{mm}^2$

Step3: Substitute values into formula

Use height $= 11$ mm, base area $= 216$ $\text{mm}^2$.
$V = \frac{1}{3} \times 216 \times 11$

Step4: Compute final volume

First calculate $\frac{1}{3} \times 216 = 72$, then $72 \times 11 = 792$

Answer:

792 cubic millimeters
