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?

Step 1. First, find the total width and length of the patio in inches. Step 1. First, find the area of the patio in square cm.

Step 1a. Convert the width and length in meters to cm:
Step 1a. Convert the portion of width and length width: 5 m:
that is expressed in feet to inches: length: 6 m:
width: 16 ft.:
length: 19 ft.: Step 1b. Find the area of the patio in square cm
by multiplying its width by its length:
Step 1b. Add these values to the portion of the width
and length of the patio expressed in inches
to find totals:
total width: Step 2. Find the area of each brick in square cm
total length: by multiplying its width by its length:

Step 2. Find the area of the patio in square inches by
multiplying its total width by its total length: Step 3. Find the number of bricks needed by dividing
the patio area by the brick area (round up to
the nearest whole brick):
Step 3. Find the area of each brick in square inches bricks
by multiplying its width by its length:

Step 4. Find the number of bricks needed by dividing
the patio area by the brick area (round up to
the nearest whole brick):
