A) \[0.550{{m}^{3}}\]
B) \[0.577{{m}^{3}}\]
C) \[0.678{{m}^{3}}\]
D) \[0.750{{m}^{3}}\]
Correct Answer: B
Solution :
[b] Volume of the pyramid \[=\frac{1}{3}\] (Area of the base) \[\times \] height \[=\frac{1}{3}\left( \frac{\sqrt{3}}{4}\times 1\times 1 \right)\times 4{{m}^{3}}\] \[=\frac{1}{\sqrt{3}}=\frac{1}{3}.\sqrt{3}=\frac{1.732}{3}\,\,{{m}^{3}}\] = 0.577 m3
