Question 21. The construction uses 11 identical bricks. The construction has a length of 100 centimeters and a width of 60 centimeters. What is the size of each of the bricks? To solve this, let's look at this part of the diagram. With this, we know that 60 centimeters is equal to one long side and two short sides of one of the bricks. So with this, we can start looking at all of our options. Option A has a brick that is 8 centimeters by 40 centimeters, which we could do 8 plus 40 plus 8, because that is two short sides and one long side. That does not equal 60 centimeters, so that cannot be the answer. Next up, we have a brick that is 10 centimeters by 40 centimeters, which, when added up together, is 60 centimeters. That is a potential solution. We do option C, 12 plus 40 plus 12, does not equal 60. 8 plus 44 plus 8 does equal 60. D is also a potential solution. And finally, E, 10 by 50, does not give us 60. That is not a potential brick. Next, let's look slightly over in our diagram and notice that 60 centimeters is also equal to six short sides of the bricks. So, to solve this, we simply need to do one of the short sides of option B or D. Let's look at D first. We have six When we add these together, we do not get a total of 60, so D cannot be the answer. This only leaves us with one potential solution, which will be B.
