What is the maximum volume of a pyramid that can fit inside a cube that has side 18 cm long?

A) 5832 cm3
B) 2916 cm3
C) 1944 cm3
D) 972 cm3

Respuesta :

Formula for Volume of cube= 1/3 x area of base x height
as base and height are the same:
So,
Base = 18 cm
Height = 18 cm
Area of base = Base^2
Area of base = 18^2
Area of base = 324 cm
Putting all the values into the formula:
1/3 x 324 x 18 
=6 x 324 
= 1944 cm^3
So according to above explanation
C) 1944 cm3, is the correct answer.

The maximum volume of the pyramid is 1944 cm³, so the correct option is C.

How to find the volume of the pyramid?

For a pyramid of base B and height H, the volume is:

A = B*H/3.

In this case, because the pyramid must be inside a cube of side length of 18cm, we know that the maximum base of our pyramid is a base of 18 cm by 18 cm, and the height is also 18 cm.

Then the maximum volume is:

V = (18 cm*18 cm)*18 cm/3 = 1944 cm³

So the correct option is C.
