Box BPrice per cubic unit ($in3)=$

Which box is cheaper per cubic unit? Type A or B
First, calculate the volume of each box:
Volume Box A = 16 in. * 4 in. * 10 in. = 640 in3
Volume Box B = 10 in. * 2 in. * 8 in. = 160 in3
Next, find the unit price for each box:
Box A Price per cubic unit ($in3) = $6.00 / 640 in3 = $0.009375 per in3
Box B Price per cubic unit ($in3) = $2.00 / 160 in3 = $0.0125 per in3
Comparing the prices, we can see that Box A is cheaper per cubic inch. So, Box A gives you more cereal for your money.
