One bridge post weighs 4567.5 pounds.
"The volume of cuboid is V = l × w × h,
where l is the length, w is the width and h is the height"
For given example,
We have been given a cement bridge post is 24 inches square and 15 feet 9 inches in length.
The base area is 24 inches square i.e., 2 sq. ft.
and the length is 15ft 9 inches i.e., 15.75 ft.
The base area is,
⇒ A = b × h
⇒ A = 2ft.
Using the formula of the volume of cuboid,
⇒ V = l × b × h
⇒ V = 15.75 × 2
⇒ V = 31.5 cu. ft.
We have been given the cement weighs 145 pounds per cubic foot
For 31.5 cu. ft.,
31.5 × 145 = 4567.5 pounds
So, one bridge post weighs 4567.5 pounds.
