Jude says that the volume of a square pyramid with base edges of 12 in and a height of 10 in is equal to the volume of a cylinde
Lapatulllka [165]

Answer:

No, not correct

Step-by-step explanation:

Square pyramid volume:  (1/3) (base area)(height).  In this case,

V = (1/3)*(12 in)^2*(10 in) = 480 in^3 = 480 in^3

Cylinder volume:  (base area)*(height).  In this case,

V = (3.14)*(6.77 in)^2*(10 in) = 452.12 in^3.

No, Jude is not correct; the 480 in^3 volume of the square pyramid is not the same as the 452.12 in^3 volume of the cylinder.
