Question

You are going to use an incline plane to lift an heavy object to the top of a shelving unit with a height of 8 ft. The base of the incline plane is 9 ft from the shelving unit. What is the length of the incline plane?​

Answer 1

We can use the formula for the length of an incline plane, which is:

length = square root of (height^2 + base^2)

In this case, the height is 8 ft and the base is 9 ft, so we can substitute those values into the formula:

length = square root of (8^2 + 9^2)
length = square root of (64 + 81)
length = square root of 145
length ≈ 12.04 ft

the length of the incline plane is approximately 12.04 ft.
