You calculate the volume of the large (whole) pyramid first
V = = 600 m^3. (1)
From it, you subtract the volume of the small cut pyramid, which is
= 2.778 m^3 (rounded). (2)
You will get finally for the volume of the frustum
= 600 - 2.778 = 577.222 m^3 (rounded). (3) ANSWER
The volume of the small pyramid is =
of the volume of the large pyramid since they are SIMILAR
solid bodies with the coefficient of similarity = .
Solved.
In solving this simple problem, you do not need to make many boring calculations
if you know this basic and useful property of the volumes of similar solid bodies.
