We know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere
if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere
if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere
examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area
2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area
3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area

Answer:
16
Step-by-step explanation:
The formula to find the volume of the right angle rectangular prism is:
V = h*w*l where:
- h is the height
- w is the width
- l is the length
= 4*8*2 = 64 cubic inches
Let V1 in cubic inches is the volume of the big rectangular prism
In the question, she made smaller rectangular prism using 1/4 of the number of cubes so the volume in cubic inches of the smaller right rectangular prism:
1/4 the Volume of of the big rectangular prism
= 1/4 V1
= 1/4*64 = 16
Hope it will find you well.
