Question

please help me with my question

Answer 1

$C)52.5m^3$

Explanation

the volume of a square pyramid is given by:

$\text{Volume}_{Pyramid}=\frac{1}{3}(side^2)\cdot heigth$

Step 1

Let

$\begin{gathered} \text{side = 5 meters} \\ heigth=6.3\text{ meters} \end{gathered}$

Now, replace.

$\begin{gathered} \text{Volume}_{Pyramid}=\frac{1}{3}(side^2)\cdot heigth \\ \text{Volume}_{Pyramid}=\frac{1}{3}((5m)^2)\cdot6.3\text{ m} \\ \text{Volume}_{Pyramid}=\frac{1}{3}(25m^2)\cdot6.3\text{ m} \\ \text{Volume}_{Pyramid}=\frac{1}{3}\cdot157.5m^3 \\ \text{Volume}_{Pyramid}=52.5m^3 \end{gathered}$

so, the answer is

$C)52.5m^3$

I hope this helps you
