Question

A manufacturer fills various size boxes with flour. Today, the boxes are 12 inches tall, 8 inches wide and 3 inches deep. They adjust the filling machine so it only fills the box until the product is 1.5 inch from the top of the box. How many cubic inches of flour will they save by not filling the box to the top?

Answer 1

Answer:

They save 36in^3

Step-by-step explanation:

First do 12*8*3 to get 288 which is the volume of the box if it was full

now that is not the answer because the people are leaving the box 1.5 in empty from the top. This means that you would subtract 1.5 from 12 to get 10.5 because that is how tall the box is and then go ahead to multiply 10.5*3*8 to get 252.

This is also not the answer because you now need to subtract 252 from 288 to get 36 which is the amount of flour the manufacturer is saving.

therefore the answer is 36in^3 ( because volume is always written cubed)

Answer 2

The volume of the box when it's filled to 3 inches deep is 12×8×3 = 288 in³

The box is filled up to 1.5 inches from the top, that means the box is filled only
3-1.5 = 1.5 inches deep

The volume of the box when it's filled to 1.5 inches deep is 12×8×1.5 = 144 in³

The number of flours saved is 288 - 144 = 144 in³
