Total volume is volumes of both square pyramids.
Volume of a tetrahedron is 1/3 times corresponding prism, and a square pyramid has two tetrahedrons.
Thus, volume of on square pyramid:
Since there are two of them, total volume is:
$\boxed{\frac{2a^2b}{3}}$
Answer:
Step-by-step explanation:
For this case we are interested on the region shaded on the figure attached.
And we can find the volume with the method of rings.
The area on this case is given by:
And the volume is given by the following formula:
For our case our limits are x=4 and x=10 so we have this:
And if we do the integral we got this:
And after evaluate we got this:
