Question

Joan is making a candle in the shape of a square pyramid. if the base edge is 5 in and the height is 6in, how much wax will they need?

Answer 1

The amount of wax they will need equal the volume of the pyramid which is;

`32\text{ }in^3`

Step-by-step explanation:

Given that the base edge of the square pyramid is 4 in and the height is 6 in;

`\begin{gathered} \text{base edge a = 4 in} \\ \text{height h = 6 in} \end{gathered}`

Recall that the formula for the volume of a pyramid is;

`V=(1)/(3)a^2h`

substituting the given values;

`\begin{gathered} V=(1)/(3)*4^2*6 \\ V=(1)/(3)*16^{}*6 \\ V=32\text{ }in^3 \end{gathered}`

Therefore, the amount of wax they will need equal the volume of the pyramid which is;

`32\text{ }in^3`
