Question

I am supposed to find the volume of this pyramid

Answer 1

For this type of problems we use the formula for the volume of a pyramid:

`\begin{gathered} V=\text{ }(1)/(3)A_bh \\ A_b\text{ is the area of the base} \\ h\text{ is the height of the pyramid} \end{gathered}`

Substituting h=12 yd and knowing that the area of a square is side*side we get that:

`\begin{gathered} A_b=\text{ 10yd }\cdot10yd=100yd^2 \\ V=(1)/(3)100yd^212yd=100yd^24yd=400yd^3 \end{gathered}`
