Tetrahedron 83144

A container shaped like a rotating cylinder with a base radius of 5 cm is filled with water. If a regular tetrahedron with an edge of 7 cm is immersed in it, how much will the water level in the container rise?

Correct answer:

h =  0.5147 cm

Step-by-step explanation:

r=5 cm S1=π r2=3.1416 5278.5398 cm2  a=7 cm V=122 a3=122 7340.4229 cm3  V = S1 h  h=S1V=78.539840.4229=0.5147 cm
