Concrete pillar

How many m³ of concrete is needed for the construction of the pillar shape of a regular tetrahedral prism, when a = 60 cm and the height of the pillar is 2 meters?

Result

V =  0.72 m3

Solution:

V=0.6 0.6 2=1825=0.72 m3V=0.6 \cdot \ 0.6 \cdot \ 2=\dfrac{ 18 }{ 25 }=0.72 \ \text{m}^3
