Question

What is the volume of a rectangular based pyramid with a height of fifteen meters and base dimensions of 4 meters and 3 meters?

sixty cubic meters

one hundred eighty cubic meters

two hundred thirty-four cubic meters

five hundred forty cubic meters

Answer 1

Do you know the equation f or the volume of a rectangular pyramid?

Answer 2

So we are given l = 3, w = 4, and h = 15

Do you know what to do with that information now?

Answer 3

Here is a picture to show.

Answer 4

Do I multiply?

Answer 5

Why yes, so a rectangle based pyramid has a volume of 1/3 times the base times the width times the height. This can be shown by the equation: V = 1/3*l*w*h

Or V = (l*w*h)/3

Answer 6

Since you have length, width, and height (4, 3, 15) respectively, you can calculate it!

Answer 7

Remember all of these are in units of meters. And that by multiplying meters three times will give your answer in meters^3.
V = (l * w * h)/3
V = (4 * 3 * 15)/3
V = 60
V = 60 m^3
