Question

I am stuck on this problem, any help would be greatly appreciated. They want me to estimate how many baseballs can fit into the bed of this pick up truck.

Baseball is 9.5 inches in diameter.

Length of the bed is 67.1 inches

Width is 50.6 inches

Height is 21.4 inches

Answer 1

The volume of the truck bed is l x w x h which is 67.1x 50.6 x 24.1= 81825.766

the volume of the baseball can be calculated as

(4/3) pi)(4.25)cubed= 321.392

so # of baseballs = 81825.766/321.392

I will let you do this calculation
