In the first question, it has asked that what are the length, width and height of prism a.
00:10
So let's try to construct prism a.
00:16
So it will be having length equals to 12 feet, width equals to 3 feet and height equals to 4 feet.
00:32
Now similarly for prism b which is adjacent to prism a, now here the length is 5 feet, the width is 2 feet and the height is 3 feet.
01:06
So this is the concept.
01:16
One can also separate this two prism, that is, if this is the prism given, so one can separate in two ways where we will cut here and we will take this portion as a one part and the another portion as the second part.
01:40
Now in the other case, when we take these, let's say the red portion, so it will be having length l equals to 6 feet and width equals to 3 feet and height equals to h equals to 5 feet.
02:19
And above that when we take the other one other prism here in this case the length will be 7 feet the height and width will be 3 feet and 4 feet so that's the concept now coming to the question number 3 we have to calculate the volume now we have to take this cut so volume of let's say this is part a and this is part b...
