Problem:
Mark C for correct and X for incorrect.
a) The total surface area of two rectangular prisms is equal.
b) The total surface area of two rectangular prisms is not equal.
c) The lateral surface area of two rectangular prisms is equal.
d) The lateral surface area of two rectangular prisms is not equal.
Solution Method:
- Apply the calculation method:
+ The lateral surface area of a rectangular prism is equal to the perimeter of the base multiplied by the height
+ The total surface area of a rectangular prism is equal to the lateral surface area plus the area of the two bases
- Calculate the lateral surface area and total surface area of each rectangular prism and then compare the results
- Based on the results, choose the corresponding Correct/Incorrect answers.
Answers:
a) C;
b) I;
c) I;
d) C.
