# Max - cone

From the iron bar (shape = prism) with dimensions 6.2 cm, 10 cm, 6.2 cm must be produced the greatest cone.
a) Calculate cone volume.
b) Calculate the waste.

Result

V =  100.64 cm3
x =  322.01 cm3

#### Solution:

$V_1 = \dfrac13 \pi (\min(6.2, 10)/2)^2 \cdot 6.2 = 62.3941244954 \ cm^3 \ \\ V_2 = \dfrac13 \pi (\min(10, 6.2)/2)^2 \cdot 6.2 = 62.3941244954 \ cm^3 \ \\ V_3 = \dfrac13 \pi (\min(6.2, 6.2)/2)^2 \cdot 10 = 100.63568467 \ cm^3 \ \\ V = \max(V_1,V_2, V_3) = 100.64 \ \text{cm}^3$
$x=6.2 \cdot \ 10 \cdot \ 6.2- 62.3941244954=322.01 \ \text{cm}^3$
