How many vertices does a rectangular prism have?(a cube is a rectangular prism with congruent square faces)
-
6
-
8
-
12
-
4
Correct Answer
A. 8Explanation
A rectangular prism is a three-dimensional shape that has six faces, and each face is a rectangle. The number of vertices of a rectangular prism can be determined by counting the number of corners or points where the edges of the faces meet. Since each face of a rectangular prism has four corners, and there are two congruent faces for each corner, the total number of vertices is 4 multiplied by 2, which equals 8. Therefore, the correct answer is 8.Rate this question:
