It is asking you to move the right formula with its match.
Formula for a cylinder: π*R^2*H
So the first option goes to the first shape.
Example:
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer.
Formula for a square: l*w*h
So the 4th option goes with the 2nd shape.
Example: l=5 w=5 h=5
(Length * Width * Hieght)
5*5*5=125 for the answer.
Formula for a cone is: 1/3π*r^2*h
So the second option goes to the 3rd shape.
Example: r=3 h=11
π≈3.14
33 is your answer.
Formula for the pyramid would be: 1/3*b*h
So the 3rd option would go to the 4th shape.
Example:
b=2 h=10
Rounded: 6.6

Answer:
The first step that we are going to do is to solve the area of the top rectangle. We are given a width of 15 cm and a length of 25 cm so we can just multiply them against each other to get the area.
The second side that we are going to solve for is the bottom rectangle. We are given a width of 12 cm and a length of 25 cm so lets just multiply them against each other to get the area.
The next area that we are going to determine is the back rectangle which has a width of 9 cm and a length of 25 cm so lets just multiply them against each other to get the area.
The final area that we have to determine are the side triangles. After determining the area of one triangle we will have to multiply it by 2 to get the area for both of the triangles. We are given a base of 12 cm and a height of 9 cm so lets just use the formula to find the area.
Multiply it by two to get the area for both of the triangles.
Finally, we are onto the last part which is to add up all of the areas and get the surface area after we combine everything.
Therefore, our final answer is option B, 1008
Hope this helps!
