(ma 912 gr.4.5)
calculate the volume of the pyramid.
volume: cubic units

Explanation:

Step1: Find base - area

The base of the pyramid is a rectangle with length $l = 12$ and width $w=10$. The area of the base $B$ is given by the formula $B=l\times w$. So, $B = 12\times10=120$.

Step2: Use volume formula

The volume $V$ of a pyramid is given by the formula $V=\frac{1}{3}Bh$, where $h = 8$ is the height of the pyramid. Substitute $B = 120$ and $h = 8$ into the formula: $V=\frac{1}{3}\times120\times8$.

Step3: Calculate volume

First, $\frac{1}{3}\times120 = 40$, then $40\times8=320$.

Answer:

320
