Question

The base of the prism is an equilateral triangle of side $8cm$ and height $12cm$. Find its volume

• A. $220.13cc$
• B. $332.554cc$
• C. $250cc$
• D. $150cc$

Answer 1

The correct option is B $332.554cc$

$\Rightarrow$ Area of equilateral triangle $=\frac{\sqrt{3}}{4}\times (side{)}^2$

$=\frac{\sqrt{3}}{4}\times (8{)}^2$

$=\frac{\sqrt{3}}{4}\times 64$

$=16\sqrt{3}c{m}^2$

$=27.713c{m}^2$

$\Rightarrow$ The volume of prism $=A\times h$

$=27.713\times 12$

$=332.554c{m}^3$.

$=332.554cc$
