We have two air shipments from two different customers $($Shipment $1$: total volume $15$m$3.$ Shipment $2$: total volume $20$m$3).$ We need to estimate how many M$1$ pallets we need to transport those shipments.

Question $6$ options:

$1)$

$15$m$3-$: $19\mathrm{.}19$m$3=0\mathrm{.}78=1$ M$1$ pallet

$2)$

$(15$m$3+20$m$3)-$: $16\mathrm{.}16$m$3=2\mathrm{.}17=3$ M$1$ pallets

$3)$

$16\mathrm{.}16$m$3-$: $35$m$3=0\mathrm{.}46=1$ M$1$ pallet

$4)$

$20$m$3-$: $16\mathrm{.}16$m$3=1\mathrm{.}24=2$ M$1$ pallets
