<h2>Answer:</h2>

The volume is 1251.7 cubic inches.

Step-by-step explanation:

To find the volume of the given figure, we will find the volume of the cuboid and a hemisphere. we will add both the volumes to get the final answer.

<h2>Volume of cuboid:</h2>

The dimensions are given as :

9 inches by 10 inches by 11 inches

So, volume = $9 \times10 \times11=990$ cubic inches

<h2>Volume of hemisphere:</h2>

The radius is given as 5 inches

V = $\frac{2}{3} \pi r^{3}$

= $\frac{2}{3} \times3.14 \times5 \times5 \times5=261.67$ cubic inches

Now total volume of the figure is :

$990+261.67=1251.67$ cubic inches and rounding to nearest tenth we get 1251.7 cubic inches.

Try for the square on the bottom multiply 9 by 10 by 11 then add the volume to the answer of 196.25 to get your volume of the whole shape.
