The value of g = 144 solved by using direct proportion.
<h3>
What is a direct proportion?</h3>
Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝.
Given that,
h =
, j =
, g = 4
g ∝ hj
g = khj
where k is a constant.
4 = k×
×
k = 24
Also given that,
g = ? , h =2, j = 3
g = khj
g = 24×2×3
g = 144
Hence, The value of g = 144.

Step-by-step explanation:
1) 6s^2
(s mean the length of each side, s=7)
= 6x7^2
= 294
2) 2(3)(2)+2(1)(2)+2(3)(1)
(l=length, w=wide, h=height)
= 12+4+6
= 22
3) 4(π)12^2
(r=radius)
= 576
