Question

volume cubic units

Explanation:

Step1: Calculate base - area

The base is a rectangle with length $l = 12$ and width $w = 10$. The area of a rectangle $A_{base}=l\times w$. So, $A_{base}=12\times10 = 120$.

Step2: Use volume formula for a pyramid

The volume formula for a pyramid is $V=\frac{1}{3}A_{base}h$, where $h = 8$. Substitute $A_{base}=120$ and $h = 8$ into the formula. $V=\frac{1}{3}\times120\times8$.

Step3: Calculate the volume

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

Answer:

320
