Question

You have been hired to lay a patio with bricks. The first thing you do is measure the patio. You find that the dimensions are16 ft and 3 in wide by 19 ft and 8 in long. The customer wants you to order the brick from a company that uses only metrics. On the website the brick that the customer wants measures 9.5 cm wide and 20 cm long. The brick company will add 10% to your number to account for any waste. The number of bricks you need to give them is the minimum number of full bricks you would need to order to make the patio based on the measurements.  Use the following steps to help you solve this problem. Convert the dimensions of the patio into inches and then find the area of the patio in inches by multiplying the width x length. Convert the brick's dimensions into inches. Afterwards use the dimensions in inches to find the area of the brick. Find the minimum number of full bricks needed by dividing the area of the patio by the area of the brick. Round answer to the nearest whole number. How many bricks will you order from the company

Answer 1

Explanation:

To find out how many bricks you need to order from the company, follow these steps:

Step 1: Convert the dimensions of the patio into inches:

The width of the patio is 16 ft and 3 in, which is equal to (16 x 12) + 3 = 195 inches.

The length of the patio is 19 ft and 8 in, which is equal to (19 x 12) + 8 = 236 inches.

Step 2: Find the area of the patio in square inches:

Multiply the width (195 inches) by the length (236 inches) to get the area of the patio: 195 x 236 = 45,960 square inches.

Step 3: Convert the brick's dimensions into inches:

The width of the brick is 9.5 cm, which is equal to 3.74 inches (since 1 cm = 0.3937 inches).

The length of the brick is 20 cm, which is equal to 7.87 inches.

Step 4: Find the area of the brick in square inches:

Multiply the width (3.74 inches) by the length (7.87 inches) to get the area of the brick: 3.74 x 7.87 = 29.38 square inches.

Step 5: Find the minimum number of full bricks needed:

Divide the area of the patio (45,960 square inches) by the area of the brick (29.38 square inches) to find the minimum number of full bricks needed: 45,960 / 29.38 = 1,564.76.

Step 6: Round the answer to the nearest whole number:

Since you can't order a fraction of a brick, round the answer to the nearest whole number. In this case, you would need to order 1,565 bricks from the company.

So, you would need to order 1,565 bricks from the company.
