Question

Let us consider a rather routine problem of laying a brick patio. Use a thousands comma where applicable. ENGLISH SYSTEM VS. METRIC SYSTEM Problem: How many bricks 3.75 in. wide × 8 in. long Problem: How many bricks 9.5 cm wide × 20 cm long are required to cover a patio 16 ft. 3 in. wide are required to cover a patio 5 meters wide by 19 ft. 8 in. long? by 6 meters long?

Answer 1

To find the number of bricks required to cover the patio, calculate the area of the patio and divide it by the area of one brick. For the English system problem, the patio is 16 ft. 3 in. wide by 19 ft. 8 in. long. For the metric system problem, the patio is 5 m wide by 6 m long.

Step-by-step explanation:

To find the number of bricks required to cover the patio, we need to calculate the area of the patio and divide it by the area of one brick.

For the English system problem, the patio is 16 ft. 3 in. wide by 19 ft. 8 in. long. Converting this to inches, the patio is 195 in. wide by 236 in. long. The area of the patio is 46020 in².

The brick is 3.75 in. wide by 8 in. long. The area of one brick is 30 in².

Dividing the area of the patio by the area of one brick, we get 1534 bricks rounded to the nearest whole number.

For the metric system problem, the patio is 5 m wide by 6 m long. The area of the patio is 30 m².

The brick is 9.5 cm wide by 20 cm long. The area of one brick is 190 cm².

Dividing the area of the patio by the area of one brick, we get 158 bricks rounded to the nearest whole number.
