What are the dimensions of a triangular pyramid with the volume of 122ft?

Answer 1

Volume is measure in CUBIC feet.

I assume you mean a pyramid of volume 122 cu ft.

volume_pyramid = 1/3 area_base x height.

= 1/3 x 1/2 x base_triangle x height_triangle x height_pyramid

→ base_triangle x height_triangle x height_pyramid = 6 x volume_pyramid

So pick any two values for base_triangle and height_triangle (both greater than zero), and you can calculate height of the pyramid by:

height_pyramid = 6 x 122 ft3 ÷ base_triangle ÷ base_triangle

= 732 ft3 ÷ base_triangle ÷ base_triangle

examples:

(base_of_triangle) 1 ft by (height_of_triangle) 1 ft by (height_of_pyramid) 122 ft

(base_of_triangle) 2 ft by (height_of_triangle) 1 ft by (height_of_pyramid) 61 ft
