To find the length of the ramp, we need to measure the diagonal of the rectangular prism. Using the Pythagorean theorem, we can find the length of the diagonal:
diagonal^2 = length^2 + width^2 + height^2
diagonal^2 = 70^2 + 35^2 + 50^2
diagonal^2 = 4900 + 1225 + 2500
diagonal^2 = 8625
diagonal ≈ √8625
diagonal ≈ 92.9 cm
So the ramp needs to be approximately 92.9 cm long. Therefore, the correct answer is 92.9 cm.
Melissa has a gerbil that lives in a cage in the shape of a rectangular prism. She wants to put a ramp in the cage to give her gerbil exercise. The cage has a length of 70 cm, a width of 35 cm, and a height of 50 cm. How long does the ramp need to be to fit diagonally in the cage? Round the answer to the nearest tenth.(1 point)
