Question

How many cubic feet of cement are in a rectangular cement slab that is 0.5 feet thick and measures 20 feet long and 10 feet wide?

Answer 1

The rectangular cement slab measuring 20 feet by 10 feet and 0.5 feet thick contains 100 cubic feet of cement.

Step-by-step explanation:

The volume of the cement slab that is 0.5 feet thick, 20 feet long, and 10 feet wide can be calculated using the formula for the volume of a rectangle, which is length x width x height. So, the volume in cubic feet would be:

Volume = 20 feet (length) x 10 feet (width) x 0.5 feet (thickness)
Volume = 100 cubic feet.

Therefore, there are 100 cubic feet of cement in the slab.

To find the volume of the cement slab, we need to multiply the length, width, and thickness of the slab together.

The volume formula for a rectangular prism is V = l * w * h, where V is the volume, l is the length, w is the width, and h is the height.

In this case, the length is 20 feet, the width is 10 feet, and the thickness is 0.5 feet. Plugging these values into the formula, we get:

V = 20 * 10 * 0.5 = 100 cubic feet.

Answer 2

To find the volume of the rectangular cement slab, multiply the length, width, and thickness of the slab. In this case, the volume is 100 cubic feet.

Step-by-step explanation:

To find the volume of the rectangular cement slab, we multiply the length, width, and thickness of the slab. The volume formula for a rectangular object is V = l * w * h. In this case, the length (l) is 20 feet, the width (w) is 10 feet, and the thickness (h) is 0.5 feet. Plugging these values into the formula, we get V = 20 * 10 * 0.5 = 100 cubic feet.

It is calculated using the formula, Perimeter of Rectangle = 2 (Length + Width). The area of a rectangle is the region covered within its boundary and this can be calculated using the formula, area of rectangle = length × width.

The formal formula is V=L×W×H; sometimes, this is written as V=LWH. This means volume equals length times width times height. Length, width, and height refer to the differing dimensions of the rectangular prism.

Area of rectangle is equal to the product of its length and width. Suppose, length of rectangle is 5cm and width is 4 cm, then the area will be: Area = 5cm x 4cm = 20 sq.cm.
