Percentage 3481

We turned a sphere with the largest possible radius from a cube with an edge length of 8 cm. Calculate the volume of the cube, the ball, and the percentage of waste when turning.

Correct answer:

V1 =  512 cm3
V2 =  268.0826 cm3
p =  47.6401 %

Step-by-step explanation:

a=8 V1=a3=83=512 cm3
r=a/2=8/2=4 V2=4/3π r3=4/3 3.1416 43=268.0826 cm3
p=100 (V1V2)/V1=100 (512268.0826)/512=47.6401%
