Given a square pyramid with a height of 21 feet and a volume of 3969 cubic feet, find the length of one side of the square base.

The length of one side of the square base is 24 feet.

Step-by-step explanation:

Given:

Volume of square pyramid(V) = 3969 cubic feet, and its height(h) = 21 feet.

Now, we need to find the length of one side(a) of the square base.

So. by putting the formula of square pyramid we get our length of one side(a):

Dividing both sides by 7 we get:

Using square root both sides we get:

a = 24 feet (approximately).

Therefore, the length of one side of the square base is 24 feet.

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
