Question

Hi there. The previous tutor could not help me on the last two parts of this question.

Answer 1

In order to calculate the area of the base, we use the formula

`\begin{gathered} A_b=s^2 \\ then,\text{ } \\ A_b=(18ft)^2 \\ A_b=324ft^2 \end{gathered}`

then, the volume of the square pyramid is found through the formula

`\begin{gathered} V=(1)/(3)* A_b* h \\ \end{gathered}`

using the two previous answers,

`\begin{gathered} V=(1)/(3)*324ft^2*3√(7)ft \\ V=324√(7)ft^3 \\ V\approx857.22ft^3 \end{gathered}`
