18 * 12 = 216 sq ft; 216 / 450 = 0.48 or 1/2 slab.
Joe needs 460 paving slabs to surrond the pond.
40 square feet
To find the number of 1-meter paving slabs needed, first calculate the area of the garden by multiplying its length and width: 15 meters × 10 meters = 150 square meters. Since each paving slab covers 1 square meter, you would need 150 paving slabs to cover the entire garden area.
90,000
You multiply the width by the length to get the area. In this case the answer would be a 45 square foot garden.

It's a trick question: None. If the width of the garden is 10 and the width of the slab is 20, the slab cannot fit into the garden without being physically changed.
The answer will vary slightly depending on assumptions: will the slabs have a space between them, and will you be cutting the slabs to fill fractions. 21 feet is equal to 14.2 of the 450 mm slabs. 19 feet is equal to 12.9 of the slabs. To complete the rectangular area, 14.2 x 12.9 = 183 slabs.
how many 300x300 mm tiles in a square metre
To determine how many slabs of stone you need, first convert the area from square feet to square inches. Since 1 square foot equals 144 square inches, 133 square feet is 133 x 144 = 19,152 square inches. Then, divide the total area by the area of one slab: 19,152 ÷ 40 = 478.8. Therefore, you would need 479 slabs of stone to cover 133 square feet, rounding up to the nearest whole slab.
Depends on the linear dimensions of both the slabs and the ground.
The answer will depend on the size of the patio slabs.
