Question

Find the volume of the triangular pyramid to the nearest whole number.HighlightA)181 in 3B)361 in 3722 inD)1,082 in 3what's the answer

Answer 1

the volume of a pyramid is

`V=(1)/(3)Ah`

where A is the area of the basis and h is the height of the pyramid.

`A=\frac{12.3\text{ in }*10\text{ in}}{2}=61.5in^2`

Then the volume is

`\begin{gathered} V=(1)/(3)(61.5in^2)(17.6in) \\ =360.8in^3 \end{gathered}`

Then rounding the number, the answer is B).
