Answer:
<u>For the first answer (A)</u>
The area of the base is the area of the 8 by 4 rectangle, minus the missing 2 by 2 square in the top-right. This is 8*4-2*2=32-4=28 square centimeters.
<u>For the second answer (B)</u>
The volume of the prism is the base area multiplied by the height, or 28*10=280 cubic centimeters.
V = 2ab + 2ca + 2bc
2ab + 2ca = V - 2bc
2a * b + c = V - 2bc
Answer: a = v - 2bc / 2 * b + c
