Answer:
n = 5
Step-by-step explanation:
Coordinate of P = (n,3)
R is on y-axis & the y-coordinate of P & R are equal. So coordinate of R = (3,0)
Coordinate of Q = (n,-2)
Using distance formula,
Distance between P & Q =


Distance between P & R =


But in question it is given that distance between P & Q is equal to the distance between P & R. So,

Volume is just length x width x height. 5 x 6 x 7 is 210. 210cm
Well the factors of "72" is→ 1,2,3,4,6,8,9,12,18,24,36,72
To find the factor(s) "72" just write out the muliples that equals 72
