Question

ANSWER ( TRUE or FALSE )

1- The prismoidal method for calculating volume will always give one a smaller volume than the average end area method between the same two x-sections.

2- The slope that is usually written on a slope stake is reduced to decimal like .33 instead of 3:1 (Run:Rise).

3- Information that is shown on a slope stake can be calculated in the office using a land modeling program such as Civil 3d as long as the ground is modeled and the design is input

4- The information that is needed for a typical slope stake can be calculated on the fly using a level, tape, set of plans showing the design, and a bench mark or temporary bench mark in the area.

Answer 1

1- false, prismoidal method will give higher volume than the average end area method between the same two x-sections. Prismoidal method give more exact value also. Prismoidal method is used when there are odd number of x-section area. but if there are even number of x-section area then the last section is solved using trapezoidal method while other same as prismoidal method.

2- false, the slope is usually written on a slope stake as Run:Rise.

3- True, If the ground is modeled properly( like benchmark is set, pivot point is set and start and end point are mentioned ) and the design is input in a land modeling program.

4- true, the information that is needed for a typical slope can be calculated on the fly using a level, tape, set of plans showing the design, and a benchmark or temporary bench mark in the area.
