How many loaded pallets in the shape of 1-meter cubes could you load in a semitrailer that has inner dimensions 2 meters wide by 10 meters long by 3 meters high?

To solve this we are going to use the formula for  a rectangular prism: 
where
is the volume
is the width 
is the height 
is the length 

We know from our problem that our semitrailer has inner dimensions 2 meters wide by 10 meters long by 3 meters high, so , , and . Lets replace those values in our formula to find :




Now to find how many pallets we could load in the semitrailer, we just need to divide the volume of the volume of the semitrailer by the volume of one pallet:


We can conclude that we could load 60 pallets in the semitrailer.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
