Megan Wu · Answer 1

Step-by-step explanation:

First you need to find the volume of the rectangle.

V=LHW

V=2*4*3

V=24

Then you need to find the volume of the cone

V=1/3 pi r^2h

V=1/3 pi 5^2 (9)

V=1/3 pi 25 (9)

V = 1/3 pi 225

V=1/3 706.5

V=235.5

Now divide 235.5 by 24 and you get 9.8125

So he needs 10 blocks
