Answer:
520/3 cubic feet
Step-by-step explanation:
You can divide this figure into 2 parts for easy calculation; a pyramid and a rectangular prism. You can find the volume of the rectangular prism by multiplying together all of the side lengths. 3*4*10=120 ft^3. To calculate the volume of a pyramid, you simply need to use the formula [tex]\frac{l\cdot w\cdot h}{3}[/tex], which in this case is [tex]\frac{4\cdot 10 \cdot 4}{3}=\frac{160}{3}ft^3[/tex]. Adding the 120 cubic feet from earlier, you get a total of [tex]\frac{520}{3}ft^3\approx 173.3[/tex]. Hope this helps!
