Question

If the area of base of a hollow triangular prism is $40$ ${\text{cm}}^2$ and height is $12$ $\text{cm}$, then what is the capacity of prism?

• A. $480$ ${\text{cm}}^3$
• B. $400$ ${\text{cm}}^3$
• C. $320$ ${\text{cm}}^3$
• D. None of the above

Answer 1

The correct option is A $480$ ${\text{cm}}^3$

Given,
Area of base $=40$ ${\text{cm}}^2$
Height $=12$ $\text{cm}$.

Capacity of prism $=$ Area of base $\times$ Height
$=40\times 12=480{\text{cm}}^3.$
