Multiply the width times the length times the height (W x L x H). You can also use our volume calculator to find cubic yardage of a space. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.

Measure the length and width of your driveway in feet. Multiply the length by the width to get surface area and divide the result by three because 4 inches is 1/3 of a foot. You now have the volume of gravel needed in cubic feet. Divide the volume in cubic feet by 27 because there are 27 cubic feet in a cubic yard.

When calculating the average width of the pour, we measure the width every 6 inches along the entire work piece and then divide by the total number of width measurements you took to determine our average. You can also divide the cubic inches by 61 to determine the total number of litres needed.

For larger decks, you can calculate the total square footage of decking you need by multiplying the length of the deck surface times the width. Allow for overhangs. Then buy enough lineal feet of decking to make up the deck area plus the waste allowance.

Just break out your measuring tape—or a laser measure—to get its length and width. Multiply the width by the length and voila! You have the square footage.

Calculate Concrete Volume With the volume of the submerged post and the volume of the hole figured out, subtract the post volume from the hole volume and you will have the volume of concrete needed for each hole. Simply multiply that amount times the number of posts to get a total quantity.

Calculate how many drywall sheets you will need by dividing the total square footage of area by 32 (if you're using 4-by-8 sheets) or by 48 (if you're using 4-by-12 sheets). If you want to get the cost, just multiply the total number of sheets by the price per sheet. Remember to add local taxes and delivery charges.

To do so, use a tape measure to determine the room's length and width. Then multiply the length by the width to get your square footage. For instance, if the room is 12 feet wide and 12 feet long, you will need enough flooring for 144 square feet (12×12=144).

One 50-pound bag of Quikrete Fast Setting Concrete Mix yields about . 375 cubic feet. For example, if you need to cover 33.333 cubic feet, using 60-pound bags of concrete, divide 33.333 cubic feet by . 45 cubic feet to get 74.07 total bags of concrete.

The mix: 1:3:6 for cement: fine aggregate (sand): coarse aggregate (granite) by mass (kg). Therefore, The mass of cement required= 0.0228 * 1440 = 32.832 kg. The number of bags of cement required= 32.832/50 = 0.66 bag (ie 1 bag of cement is required to cover a 1m * 1m * 0.15m floor in a concrete mix 1:3:6).
