A right rectangular pyramid has a altitude of 22.3inches ,a length of 6.75,and a width of 10.25inches .what is the volume of the pyramid in cubic inches
The volume of a pyramid can be calculated using the formula V = (1/3) * base area * height.
To find the base area of the rectangular pyramid, multiply the length by the width:
Base area = 6.75 inches * 10.25 inches = 69.1875 square inches.
Now, substitute the values into the formula:
V = (1/3) * 69.1875 square inches * 22.3 inches.
Multiply to find the volume:
V = 5.72916666667 cubic inches.
Rounding to the nearest hundredth, the volume of the pyramid is approximately 5.73 cubic inches.
