You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x 4 in. x 2 in., how many bricks will you need? (Remember to round up.)

Question

You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x 4 in. x 2 in., how many bricks will you need? (Remember to round up.)

Answer 1

The wall is 174 x 66 x 6 inches. That is 29 x 16.5 x 3 bricks.

If we have to round up (no partial bricks reused), then that is 29 x 17 x 3 = 1479 bricks.

Answer 2

To find the number of bricks needed, we need to calculate the total volume of the wall and divide it by the volume of a single brick.

1. Convert the dimensions of the wall to inches:
Length = 14.5 ft. * 12 in./ft. = 174 in.
Height = 5.5 ft. * 12 in./ft. = 66 in.
Width = 0.5 ft. * 12 in./ft. = 6 in.

2. Calculate the volume of the wall:
Volume = Length x Height x Width
= 174 in. x 66 in. x 6 in.
= 68604 in³

3. Convert the dimensions of a brick to inches:
Length = 6 in.
Height = 4 in.
Width = 2 in.

4. Calculate the volume of a single brick:
Volume = Length x Height x Width
= 6 in. x 4 in. x 2 in.
= 48 in³

5. Divide the volume of the wall by the volume of a single brick:
Number of bricks = Volume of the wall / Volume of a single brick
= 68604 in³ / 48 in³
≈ 1429.25

Rounding up to the nearest whole number, you will need approximately 1430 bricks to construct the wall.

Answer 3

To calculate the number of bricks needed, we need to determine the volume of the wall and the volume of each brick.

First, let's calculate the volume of the wall:

Length of the wall = 14.5 ft.
Height of the wall = 5.5 ft.
Width of the wall = 0.5 ft.

To find the volume, multiply the length, height, and width:

Volume of the wall = Length x Height x Width
= 14.5 ft. x 5.5 ft. x 0.5 ft.

Next, let's calculate the volume of each brick:

Length of the brick = 6 inches = 0.5 ft.
Height of the brick = 4 inches = 0.33 ft.
Width of the brick = 2 inches = 0.17 ft.

Volume of the brick = Length x Height x Width
= 0.5 ft. x 0.33 ft. x 0.17 ft.

Now, divide the volume of the wall by the volume of each brick to get the number of bricks needed:

Number of bricks = Volume of the wall / Volume of each brick
= (14.5 ft. x 5.5 ft. x 0.5 ft.) / (0.5 ft. x 0.33 ft. x 0.17 ft.)

Finally, calculate the result:

Number of bricks = (14.5 ft. x 5.5 ft. x 0.5 ft.) / (0.5 ft. x 0.33 ft. x 0.17 ft.)

After performing the calculation, you should get the answer to the question. Remember to round up as the instructions state.
