Two triangular pyramids are similar. the volume of the larger pyramid is 729 cm3 , and the volume of the smaller pyramid is 64 cm3. if the perimeter of the base of the smaller pyramid is 8 cm, what is the perimeter of the base of the larger pyramid? 18 cm 18 cm2 27 cm 27 cm2

  Second Option is correct.

Step-by-step explanation:

Since we have given that

Volume of larger pyramid = 729 cm³

Volume of smaller pyramid = 64 cm³

So, Ratio of volume of larger pyramid to volume of smaller pyramid is given by

So, Ratio of side of larger pyramid to side of smaller pyramid is given by

Now, Perimeter of base of smaller pyramid = 8 cm

So, We need to find the perimeter of larger pyramid.

So, it becomes,

Hence, Perimeter of the base of the larger pyramid is 18 cm².

Therefore, Second Option is correct.
