Red Seal Carpenter Practice Exam

You are building on a sloped grade. You need to build a stepped foundation and the top of the front of your foundation is 1 000 mm (39") higher than that of the rear. How many steps are required in the foundation?

1. 2

2. 3

3. 4

4. 5

The correct answer is: 4

To understand why C is the correct answer, we need to look at the dimensions of the foundation and the fact that there is a slope involved. Since the top of the front of the foundation is higher than the rear, we need to build steps to accommodate the change in elevation. The number of steps needed will depend on the height difference between the front and rear of the foundation. Option A (2 steps) and B (3 steps) may be incorrect because they do not account for the full 1 000 mm height difference between the front and rear. Option D (5 steps) may be incorrect because it may create too many and unnecessarily small steps, making it difficult to build and use effectively. Hence, C with 4 steps is the most feasible and efficient option, accounting for the sloped grade and providing adequate steps for the foundation.
