Question

determine the volume of each rectangular or triangle pyramid round to the nearest tens of necessary

Answer 1

The volume of a square pyramid is given by the equation:

$V=\frac{1}{3}\times B\times H$

Where B is the area of the base and His the high of the pyramid, the area of the square base can be calculated with the formula:

$B=L\times L=L^2$

Where L is the length of the sides of the square, let's calculate it for our figure, like this:

$B=8^2=64$

And now, let's calculate the volume of the pyramid with the first formula, like this:

$V=\frac{1}{3}\times64\times19=\frac{1}{3}\times1216=\frac{1216}{3}=405,3$

Then, the volume of the pyramid is 405,3 cubic inches
