<span>The property that is shown in the expression given in the question is commutative property. The word commutative has basically been taken from the word "commute". This means moving around and in case of this problem, it means moving around for doing the addition and getting to the right answer. I hope it helps you.</span>
For second one the answer is 14
Answer:
The amount of water she needs to pump in:
V = Base area x Height x 1/2 = (4/2)^2 x pi x 0.75 x 1/2 = 1.5pi = ~4.7 (ft3)
=> Option D is correct.
Hope this helps!

Answer:

Step-by-step explanation:
A 3D figure is given to us and we need to find the Total Surface area of the 3D figure . So ,
From the cuboid we can see that there are 5 squares in one row on the front face . And there are two rows. So the number of squares on the front face will be 5*2 = 10 .
We know the area of square as ,
Hence the area of 10 squares will be 10x² , where x is the side length of each square. Similarly there are 10 squares at the back . Hence their area will be 10x² .
Also there are in total 12 squares sideways 6 on each sides . So their surface area will be 12x² . Hence the total surface area in terms of side of square will be ,
Now let's find out the TSA in terms of side . So here the lenght of the cuboid is equal to the sum of one of the sides of 5 squares .


Hence the TSA of cuboid in terms of lenght and breadth is :-
