Ineed the answer and if you could explain step by step

umm sir where is the graff we need it to solve the problem

answer:

we need a graph to solve this. provide the graph and we will be happy to you!

step-by-step explanation:

answer:

x = 96.23   if   x is the area of the base

x =21           if x is the side length of the base

step-by-step explanation:

the volume of a square pyramid is given by

v=1/3 a^ 2 h

we know the volume is 441 and the area of the base is a^2 which is x

and the height is 1/7x

substituting these values in

441 = 1/3 (x) 1/7x

441 =1/21 x^2

multiply each side by 21

441*21 = 21*1/21 x^2

9261 = x^2

take the square root of each side

sqrt(9261) = sqrt(x^2)

x = 96.23

i am thinking you mean x is the side length on the base

we know the volume is 441 and the area of the base is a^2 which is x^2

and the height is 1/7x

substituting these values in

441 = 1/3 (x^2) 1/7x

441 =1/21 x^3

multiply each side by 21

441*21 = 21*1/21 x^3

9261 = x^3

take the cube root of each side

(9261) ^ (1/3) = (x^3)^(1/3)

21 =x
