Question

The volume of a regular triangular prism is 90 sqrt of 3 cm cube. If the radius of the inscribed circle in the base is 3cm, find the altitude of the prism. Please help. Including the drawing. Thanks.

Answer 1

What do you mean by "90 sqrt of 3 cm cube"?

Answer 2

r=3
d=2*3=6
edge of square base=6
\[volume=\frac{ 1 }{ 3 }\pi a^2h\]
\[\frac{ 1 }{ 3 }\pi 6^2h=90\sqrt{3}\]
h=?

Answer 3

Cm is raise to cube

Answer 4

90 sqrt of 3 cm^3
