Question

WILL MARK BRAINIEST!!! Charlotte wants to make a mailbox like the one shown. What is the volume of the mailbox? Round to the nearest tenth.

Answer 1

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.

Answer 2

Answer:

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.

Volume of cuboid:

The dimensions are given as :

9 inches by 10 inches by 11 inches

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

Volume of hemisphere:

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.
