How many 8 x 8 x 16 concrete blocks are needed for a foundation wall with a total perimeter of 216' and 12 courses high?

To determine the number of 8 x 8 x 16 concrete blocks needed for a foundation wall, we first need to calculate the total area of the wall that will be built.

Given that the total perimeter of the foundation wall is 216 feet and it is 12 courses high, we can calculate the total square footage of the wall.

1. Calculate the total height of the wall:

The height of each course of block is 8 inches, which is 0.67 feet (since there are 12 inches in a foot):

[

\text{Height of wall} = 12 \text{ courses} \times 0.67 \text{ feet/course} = 8 \text{ feet}

]

2. Calculate the total area of the wall:

The total area in square feet can be calculated using the perimeter and height:

[

\text{Total Area} = \text{Perimeter} \times \text{Height} = 216 \text{ feet} \times 8 \text{ feet} = 1728 \text{ square feet}

]

3. Calculate the area covered by one concrete block:

Each concrete block measures
