Area od a patio is 24 meters. sq. A patio stone is square with each side 30 cm. How many will be needed to complete the patio?

Depends on the dimensions of the patio, and whether partial stones (after cutting) may be used.

Just the simple answer is

24*100^2/30^2 = 267.7 stones.

To find out how many patio stones are needed to complete the patio, we need to calculate the area of each stone and then divide the total area of the patio by the area of each stone.

First, let's convert the dimensions to the same unit.
Each side of the patio stone is given in centimeters (cm). We should convert it to meters (m) to match the units of the patio area.

Since 1 meter is equal to 100 centimeters, we can convert the length of each side of the stone by dividing it by 100.
30 cm ÷ 100 = 0.3 meters

Now, let's calculate the area of each stone. Since the stone is square, we can just multiply the length of one side by itself.
Area of each stone = 0.3 meters × 0.3 meters = 0.09 square meters

Next, we can calculate the number of stones needed to cover the entire patio area. Divide the patio area by the area of each stone.
Number of stones needed = Total patio area ÷ Area of each stone

Since the given patio area is 24 square meters:
Number of stones needed = 24 square meters ÷ 0.09 square meters

Dividing the total area of 24 square meters by the area of each stone (0.09 square meters), we get the number of stones needed to complete the patio:
Number of stones needed = 24 ÷ 0.09

Calculating this division:
Number of stones needed = 266.67

Since we can't have a fraction of a stone, we need to round up to the next whole number. Therefore, we would need 267 patio stones to complete the patio.
