approximate the volume of the backpack that is 17in × 12 in × 4inif you need a picture I'll try to send it to help

Answers

To find volume you multiply all three dimensions by one another. We can approximate this by multiplying the smaller ones first.

12*4=48 Now multiply 48 by 10.

48*10=480 We still have 7 to deal with, so we can multiply 48 by 2 and then by 5.

48*5=240
48*2=96

Now add the three together.

480+240+96=816.

Your answer is 816.

The formula for volume would make the equation 17" x 12" x 4", which would make it 816 cubic inches.
