The volume of a square pyramid is 75 cubic feet. the base area is 15 square feet. what is the height of the pyramid?

Volume of square pyramid is given by:

Where a² is area of base and h is height of pyramid.

We are given Volume of pyramid as 75 cubic feet and area of base of pyramid is 15 square feet.

So plugging these values in the formula for volume , we have,

dividing both sides by 15,

multiplying both sides by 3 ,we have

h=6

So height of pyramid is 6 feet.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
