How many yards of concrete does it take to pour a slab 9 ft x 24ft x 2inches thick?

Answer 1

This is a volume question. So follow these steps:

1. Identify the shape. This shape is a rectangle, now go to a formula chart and find what the formula is for a rectangle under volume, It will say V=BH.
2. So lets begin. But wait these dimensions are not all equal in units so you need to convert the feet to inches. There are 12 inches in 1 foot so multiply 9 times 12= 108 and 24 times 12=288.
3. Now we can start by finding the B, area of the base. The base is a rectangle now go to the formula chart and find the formula for the rectangle under the area. A=LW. Now we can plug in the numbers, A=288*2=576.
4. Now that we found the area we can finish the formula, V=BH so we can plug in the numbers that we got V=576*108=62,208 inches cubed.
5. We have found the volume for this rectangle in inches, but the question wants the units in yards.
6. So we get the answer 62,208 and divide by 36 inches, because that is how many inches are in a yard. 62,208 divided by 36=1,728 yards cubed, the answer is cubed because we are working with a volume question.

So the answer is 1,728 yards cubed.
