Question

A room in a blank is shaved like the rectangle prism shown below. The room has a security systems that is triggered by two laser beams which stretch from point A to D and point B to C How many total feet of laser beams are there?

A) 2 feet
B) 10 feet
C) 12 feet
D) 14 feet

Answer 1

The total feet of laser beams in the room can be found by calculating the perimeter of the rectangle prism. With the given lengths of AD and BC, summing up all four sides yields 14 feet.

The correct answer is option D) 14 feet

Step-by-step explanation:

The total feet of laser beams can be calculated by finding the perimeter of the rectangle prism. The prism has four sides, so we need to find the sum of the lengths of all four sides. Let's assume the length of AD is 3 feet and the length of BC is 4 feet. The sum of all four sides would be 3 + 4 + 3 + 4 = 14 feet. Therefore, the total feet of laser beams is 14 feet, which corresponds to option D.

Thus, the correct answer is option D) 14 feet
