8 x 5 x 4 = 160m^3
to find the volume of a cube its V= W x H x L
40 x (80/100)
= 32
So answer will be 32

V=b² h/3------------ >12=9*h/3------------ >h=12/3---- >h=4
the answer is h=4 feet
<u>Given</u>:
Given that the radius of the hemisphere is 9.8 inches.
We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
The volume of the hemisphere can be determined using the formula,

where r is the radius of the hemisphere.
Substituting r = 9.8 in the above formula, we get;

Simplifying, we get;



Rounding off to the nearest tenth, we get;

Thus, the volume of the hemisphere is 1970.2 cubic inches.
